Creating a Custom Amazon EBS-Backed Linux AMI

AWS – Build your own Oracle Linux 7 AMI in the Cloud

I always like to know what is installed in the servers that I need to use for databases or Weblogic installs. Whether it is in the Oracle Cloud or in any other Cloud. One way to know is to build your own image that will be used to start your instances. My latest post was about building my own image for the Oracle Cloud (IAAS), but I could only get it to work with Linux 6. Whatever I tried with Linux 7 it wouldn’t start in a way that I could logon to it. And no way to see what was wrong. Not even when mounting the boot disk to an other instance after a test boot. My trial ran out before I could get it to work and a new trial had other problems.

Since we have an AWS account I could try to do the same in AWS EC2 when I had some spare time. A few years back I had built Linux 6 AMI’s via a process that felt a bit complicated but it worked for a PV Kernel. For Linux 7 I couldn’t find any examples on the web on how to do that with enough detail to really get it working. But while was studying for my Oracle VM 3.0 for x86 Certified Implementation Specialist exam I realized what must have been the problem. Therefore below follow my notes on how to build my own Oracle Linux 7.3 AMI for EC2.

General Steps:

  1. Create a new Machine in VirtualBox
  2. Install Oracle Linux 7.3 on it
  3. Configure it and install some extra packages
  4. Clean your soon to be AMI
  5. Export your VirtualBox machine as an OVA
  6. Create an S3 bucket and upload your OVA
  7. Use aws cli to import your image
  8. Start an instance from your new AMI, install the UEKR3 kernel.
  9. Create a new AMI from that instance in order to give it a sensible name

The nitty gritty details:

Ad 1) Create a new Machine in VirtualBox

Create an New VirtualBox Machine and start typing the name as “OL” which sets the type to Linux and version to Oracle (64 bit). Pick a name you like. I choose OL73. I kept the memory as it was (1024M). Create a HardDisk. 10Gb Dynamically allocated (VDI) worked for me. I disabled the audio as I had no use for that and made sure one network interface was available. I selected my NatNetwork type because that gives me VM access to the network and lets me access it via a Forwarding Rule on just one interface. You need to logon via VBox first to get the IP address then you can use an other preferred terminal to login. I like putty.

Attach the DVD with the Linux you want to use, I like Oracle Linux (https://otn.oracle.com), and start the VM.

Ad 2) Install Oracle Linux 7.3 on it

When you get the installation screen do not choose “Install Oracle Linux 7.3” but use TAB to add “ net.ifnames=0” to the boot parameters (note the extra space) and press enter.

Choose the language you need, English (United States) with a us keyboard layout works for me. Go to the next screen.

Before you edit “Date & Time” edit the network connection (which is needed for NTP).

Notice that the interface has the name eth0 and is disconnected. Turn the eth0 on by flipping the switch

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 16 50 42 OL7 Running Oracle VM

And notice the IP address etc. get populated:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 16 51 41 OL7 Running Oracle VM

Leave the host name as it is (localhost.localdomain) because your cloud provider will change anything you set here anyway, and press the configure button. Then choose the General tab to check “Automatically connect to this network when it is available”, keep the settings on the Ethernet tab as they are, the same for 802.1X Security tab, DCB tab idem. On the IPv4 Settings tab, leave “Method” on Automatic (DHCP) and check “Require IPv4 addressing for this connection to complete”. On the IPv6 Settings tab change “Method” to Ignore and press the “Save” button and then press “Done”.

Next change the “Date & Time” settings to your preferred settings and make sure that “Network Time” is on and configured. Then press “Done”.

Next you have to press “Installation Destination”

Now if the details are in accordance with what you want press “Done”.

Your choice here has impact on what you can expect from the “cloud-init” tools.

For example: Later on you can launch an instance with this soon to be AMI and start it with let’s say a 20 GiB disk instead of the 10GiB disk this image now has. The extra 10GiB can be used via a new partition and adding that to a LVM pool. That requires manual actions. But if you expect the cloud-init tools to resize your partition to make use of the extra 10GiB and extend the filesystem (at first launch). Then you need to change a few things.

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 26 17 OL7 Running Oracle VM

Then press “Done” and you get guided through an other menu:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 27 59 OL7 Running Oracle VM

Change LVM to “Standard Partition”

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 29 46 OL7 Running Oracle VM

And then create the mount points you need by pressing “+” or click the blue link:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 30 29 OL7 Running Oracle VM

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 33 34 OL7 Running Oracle VM

Now what you get are 3 partitions on your disk (/dev/sda). Notice that “/” is sda3 and is the last partition. When you choose this in your image the cloud-init utils will resize that partition to use the extra 10GiB and extend the filesystem on it as well. It makes sense that it can only resize the last partition of your disk. Which means that that your swap size is fixed between these partitions and can only be increased on a different disk (Or volume as it is called in EC2) that you need to add to your instance when launching (or afterwards). Leaving you with a gap of 1024MiB that is not very useful.

You might know what kind of memory size instances you want to use this image for and create the necessary swap up front (and maybe increase the disk from 10GiB to a size that caters for the extra needed swap).

I like LVM and choose to partition automatically and will use LVM utils to use the extra space by creating a third partition.

The other options I kept default:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 55 44 OL7 Running Oracle VM

And press “Begin Installation”. You then will see:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 17 58 57 OL7 Running Oracle VM

Set the root password to something you will remember, later I will disable it via “cloud-init” and there is no need to create an other user. Cloud-init will also take care of that.

I ignored the message: AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 18 00 59 OL7 Running Oracle VM and pressed Done again.

Press the “Reboot” button when you are asked to and when restarting select the standard kernel (Not UEK). This is needed for the Amazon VMImport tool. You have less then 5 seconds to change the default kernel (UEK) from booting.

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 18 13 23 OL7 Running Oracle VM

If you missed it just restart the VM.

Ad 3) Configure it and install some extra packages

Login with your preferred terminal program via NatNetwork (make sure you have a forwarding rule for the IP you wrote down for ssh)

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 06 06 10 17 49 Oracle VM VirtualBox Manager

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 06 06 10 18 16 VirtualBox Preferences

 

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 18 24 43 Port Forwarding Rules

or use the VirtualBox console. If you forgot to write the IP down you can still find it via the VirtualBox console session:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 18 27 37 OL7 Running Oracle VM

You might have noticed that my IP address changed. That is because I forgot to set the network in VirtualBox to NatNetwork when making the screenshots. As you can see the interface name is eth0 as expected. If you forgot to set the boot parameter above you need to do some extra work in the Console to make sure that eth0 is used.

Check the grub settings:

cat /etc/default/grub

And look at: GRUB_CMDLINE_LINUX (check if net.ifnames=0 is in there), and look at: GRUB_TIMEOUT. You might want to change that from 5 seconds to give you a bit more time. The AWS VMImport tool will change it to 30 seconds.

If you made some changes, you need to rebuild grub via:

grub2-mkconfig -o /boot/grub2/grub.cfg

Change the network interface settings:

vi /etc/sysconfig/network-scripts/ifcfg-eth0
Make it look like this:

TYPE=Ethernet
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
NAME=eth0
DEVICE=eth0
ONBOOT=yes
PEERDNS=yes
PEERROUTES=yes

Change dracut.conf *** this is very important. In VirtualBox the XEN drivers do not get installed in the initramfs image and that will prevent your AMI from booting in AWS if it is not fixed ***

vi /etc/dracut.conf

adjust the following two lines:

# additional kernel modules to the default
#add_drivers+=””

to:

# additional kernel modules to the default
add_drivers+=”xen-blkfront xen-netfront”

Temporarily change default kernel:

(AWS VMImport has issues when the UEK kernels are installed or even present)

vi /etc/sysconfig/kernel

change:

DEFAULTKERNEL=kernel-uek

to:

DEFAULTKERNEL=kernel

Remove the UEK kernel:

yum erase -y kernel-uek kernel-uek-firmware

Check the saved_entry setting of grub:

cat /boot/grub2/grubenv
or: grubby –default-kernel

If needed set it to the RHCK (RedHat Compatible Kernel) via:

grub2-set-default <nr>

Find the <nr> to use via:

grubby –info=ALL

Use the <nr> of index=<nr> where kernel=/xxxx lists the RHCK (not a UEK kernel).

Rebuild initramfs to contain the xen drivers for all the installed kernels:

rpm -qa kernel | sed ‘s/^kernel-//’  | xargs -I {} dracut -f /boot/initramfs-{}.img {}

Verify that the xen drivers are indeed available:

rpm -qa kernel | sed ‘s/^kernel-//’  | xargs -I {} lsinitrd -k {}|grep -i xen

Yum repo adjustments:

vi /etc/yum.repos.d/public-yum-ol7.repo

Disable: ol7_UEKR4 and ol7_UEKR3.
You don’t want to get those kernels back with a yum update just yet.
Enable: ol7_optional_latest, ol7_addons

Install deltarpm, system-storage-manager and wget:

yum install -y deltarpm system-storage-manager wget

(Only wget is really necessary to enable/download the EPEL repo. The others are useful)

Change to a directory where you can store the rpm and install it. For example:

cd ~
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh epel-release-latest-7.noarch.rpm

Install rlwrap (useful tool) and the necessary cloud tools:

yum install -y rlwrap cloud-init cloud-utils-growpart

Check your Firewall settings (SSH should be enabled!):

firewall-cmd –get-default-zone
firewall-cmd –zone=public –list-all

You should see something like for your default-zone:
interfaces: eth0
services: dhcpv6-client ssh

Change SELinux to permissive (might not be really needed, but I haven’t tested it without this):

vi /etc/selinux/config
change: SELINUX=enforcing
to: SELINUX=permissive

Edit cloud.cfg:

vi /etc/cloud/cloud.cfg
change: ssh_deletekeys:    0
to: ssh_deletekeys:   1

change:

system_info:
default_user:
name: cloud-user
to:
system_info:
default_user:
name: ec2-user

Now cloud.cfg should look like this: (between the =====)

users:
– default

disable_root: 1
ssh_pwauth:   0

mount_default_fields: [~, ~, ‘auto’, ‘defaults,nofail’, ‘0’, ‘2’]
resize_rootfs_tmp: /dev
ssh_deletekeys:   1
ssh_genkeytypes:  ~
syslog_fix_perms: ~

cloud_init_modules:
– migrator
– bootcmd
– write-files
– growpart
– resizefs
– set_hostname
– update_hostname
– update_etc_hosts
– rsyslog
– users-groups
– ssh

cloud_config_modules:
– mounts
– locale
– set-passwords
– yum-add-repo
– package-update-upgrade-install
– timezone
– puppet
– chef
– salt-minion
– mcollective
– disable-ec2-metadata
– runcmd

cloud_final_modules:
– rightscale_userdata
– scripts-per-once
– scripts-per-boot
– scripts-per-instance
– scripts-user
– ssh-authkey-fingerprints
– keys-to-console
– phone-home
– final-message

system_info:
default_user:
name: ec2-user
lock_passwd: true
gecos: Oracle Linux Cloud User
groups: [wheel, adm, systemd-journal]
sudo: [“ALL=(ALL) NOPASSWD:ALL”]
shell: /bin/bash
distro: rhel
paths:
cloud_dir: /var/lib/cloud
templates_dir: /etc/cloud/templates
ssh_svcname: sshd

# vim:syntax=yaml

With this cloud.cfg you will get new ssh keys for the server when you deploy a new instance, a user “ec2-user” that has password less sudo rights to root, and direct ssh to root becomes disabled as well as using a password for ssh authentication.

**** Remember, when you reboot now cloud-init will kick in and only console access to root will be available. Ssh to root is disabled ****
**** because you do not have an http server running serving ssh keys for the new ec2-user that cloud-init can use ****
**** It might be prudent to validate your cloud.cfg is a valid yaml file via http://www.yamllint.com/ ****

Check for the latest packages and update:

yum check-update
yum update -y

Ad 4) Clean your soon to  be AMI

You might want to clean the VirtualBox machine of logfiles and executed commands etc:

rm -rf  /var/lib/cloud/
rm -rf /var/log/cloud-init.log
rm -rf /var/log/cloud-init-output.log

yum -y clean packages
rm -rf /var/cache/yum
rm -rf /var/lib/yum

rm -rf /var/log/messages
rm -rf /var/log/boot.log
rm -rf /var/log/dmesg
rm -rf /var/log/dmesg.old
rm -rf /var/log/lastlog
rm -rf /var/log/yum.log
rm -rf /var/log/wtmp

find / -name .bash_history -exec rm -rf {} +
find / -name .Xauthority -exec rm -rf {} +
find / -name authorized_keys -exec rm -rf {} +

history -c
shutdown -h now

Ad 5) Export your VirtualBox machine as an OVA

In VirtualBox Manager:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 47 36

And select the Virtual Machine you had just shutdown:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 48 21 Export Virtual Appliance

If needed change the location of the ova to be created:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 49 21 Export Virtual Appliance

 

Ad 6) Create an S3 bucket and upload your OVA

Log in to your AWS console choose the region where you want your AMI to be created and create a bucket there (or re-use one that you already have):

https://console.aws.amazon.com/s3/home?region=eu-west-1

(I used the region eu-west-1)

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 54 33 S3 Management Console

Set the properties you want, I kept the defaults properties and permissions:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 56 05 S3 Management Console

Then press:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 07 03 21 58 51 S3 Management Console

 

Ad 7) Use aws cli to import your image

Before you can import the OVA file you need to put it in the created bucket. You can upload it via the browser or use “aws cli” to do that. I prefer the aws cli because that always works and the browser upload gave me problems.

How to install the command line interface is described here: http://docs.aws.amazon.com/cli/latest/userguide/installing.html

On an Oracle linux 7 machine it comes down to:

yum install -y python34.x86_64 python34-pip.noarch
pip3 install –upgrade pip
pip install –upgrade awscli
aws –version

Then it is necessary to configure it, which is basically (http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html):

aws configure

And answer the questions by supplying your credentials and your preferences. These are fake credentials below

AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: eu-west-1
Default output format [None]: json

The answers will be saved in two files:

~/.aws/credentials
~/.aws/config

To test the access try to do a listing of your bucket:

aws s3 ls s3://amis-share

To upload the generated OVA file is then as simple as:

aws s3 cp /file_path/OL73.ova s3://amis-share

The time it takes depends on your upload speed.

Create the necessary IAM role and policy (http://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-image-import.html):

Create a trust-policy.json file:

vi trust-policy.json
{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Principal": { "Service": "vmie.amazonaws.com" },
         "Action": "sts:AssumeRole",
         "Condition": {
            "StringEquals":{
               "sts:Externalid": "vmimport"
            }
         }
      }
   ]
}

Create the IAM role:

aws iam create-role –role-name vmimport –assume-role-policy-document file:///home/ec2-user/trust-policy.json

Create the role-policy.json file:

Change the file to use your S3 bucket (amis-share/*).

vi role-policy.json
{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Action": [
            "s3:ListBucket",
            "s3:GetBucketLocation"
         ],
         "Resource": [
            "arn:aws:s3:::amis-share"
         ]
      },
      {
         "Effect": "Allow",
         "Action": [
            "s3:GetObject"
         ],
         "Resource": [
            "arn:aws:s3:::amis-share/*"
         ]
      },
      {
         "Effect": "Allow",
         "Action":[
            "ec2:ModifySnapshotAttribute",
            "ec2:CopySnapshot",
            "ec2:RegisterImage",
            "ec2:Describe*"
         ],
         "Resource": "*"
      }
   ]
}

aws iam put-role-policy –role-name vmimport –policy-name vmimport –policy-document file:///home/ec2-user/role-policy.json

Now you should be able to import the OVA.

Prepare a json file with the following contents (adjust to your own situation):

cat imp_img.json 
{
    "DryRun": false,
    "Description": "OL73 OVA",
    "DiskContainers": [
        {
            "Description": "OL73 OVA",
            "Format": "ova",
            "UserBucket": {
                "S3Bucket": "amis-share",
                "S3Key": "OL73.ova"
            }
        }
    ],
    "LicenseType": "BYOL",
    "Hypervisor": "xen",
    "Architecture": "x86_64",
    "Platform": "Linux",
    "ClientData": {
        "Comment": "OL73"
    }
}

Then start the actual import job:

aws ec2 import-image –cli-input-json file:///home/ec2-user/imp_img.json

The command retuns with the name of the import job which you can then use to get the progress:
aws ec2 describe-import-image-tasks –import-task-ids import-ami-fgotr2g7

Or in a loop:

while true; do sleep 60; date; aws ec2 describe-import-image-tasks –import-task-ids import-ami-fgotr2g7; done

Depending on the size of your OVA it takes some time to complete. An example output is:

{
    "ImportImageTasks": [
        {
            "StatusMessage": "converting",
            "Status": "active",
            "LicenseType": "BYOL",
            "SnapshotDetails": [
                {
                    "DiskImageSize": 1470183936.0,
                    "Format": "VMDK",
                    "UserBucket": {
                        "S3Bucket": "amis-share",
                        "S3Key": "OL73.ova"
                    }
                }
            ],
            "Platform": "Linux",
            "ImportTaskId": "import-ami-fgotr2g7",
            "Architecture": "x86_64",
            "Progress": "28",
            "Description": "OL73 OVA"
        }
    ]
}

Example of an error:

{
    "ImportImageTasks": [
        {
            "SnapshotDetails": [
                {
                    "DiskImageSize": 1357146112.0,
                    "UserBucket": {
                        "S3Key": "OL73.ova",
                        "S3Bucket": "amis-share"
                    },
                    "Format": "VMDK"
                }
            ],
            "StatusMessage": "ClientError: Unsupported kernel version 3.8.13-118.18.4.el7uek.x86_64",
            "ImportTaskId": "import-ami-fflnx4fv",
            "Status": "deleting",
            "LicenseType": "BYOL",
            "Description": "OL73 OVA"
        }
    ]
}

Once the import is successful you can find your AMI in your EC2 Console:

AWS - Build your own Oracle Linux 7 AMI in the Cloud 2017 06 17 09 40 09 EC2 Management Console

Unfortunately no matter what you Description or Comment you supply in the json file the AMI is only recognized via the name of the import job: import-ami-fgotr2g7. As I want to use the UEK kernel I need to start an instance from this AMI and use that as an new AMI. And via that process (Step 9) I can supply a better name. Make a note of the snapshots and volumes that have been created via this import job. You might want to remove those later to prevent storage costs for something you don’t need anymore.

 

Ad 8) Start an instance from your new AMI, install the UEKR3 kernel

I want an AMI to run Oracle software and want the UEK kernel that has support. UEKR4 wasn’t supported for some of the software I recently worked with, thus that left me with the UEKR3 kernel.

Login to your new instance as the ec2-user with your preferred ssh tool and use sudo to become root:

sudo su –

Enable Yum Repo UEKR3

vi /etc/yum.repos.d/public-yum-ol7.repo
ol7_UEKR3
enabled=0 ==> 1

Change the default kernel back to UEK:

vi /etc/sysconfig/kernel
change:
DEFAULTKERNEL=kernel
To:
DEFAULTKERNEL=kernel-uek

Update the kernel:

yum check-update
yum install kernel-uek.x86_64

Notice the changes in grub_cmd_line that where made by the import proces:

cat /etc/default/grub

Notice some changes:

GRUB_TIMEOUT=30
GRUB_TERMINAL_OUTPUT=”console”
GRUB_CMDLINE_LINUX=”crashkernel=auto rd.lvm.lv=ol/root rd.lvm.lv=ol/swap rhgb quiet net.ifnames=0 console=ttyS0″
GRUB_DISABLE_RECOVERY=”true”

To verify which kernel will be booted next time you can use:

cat /boot/grub2/grubenv
grubby –default-kernel
grubby –default-index
grubby –info=ALL

Clean the instance again and shut it down in order to create an new AMI:

Ad 9) Create a new AMI from that instance in order to give it a sensible name

Use the instance id of the instance that you just shut down: i-050357e3ecce863e2 to create a new AMI.

To generate a skeleton json file:

aws ec2 create-image –instance-id i-050357e3ecce863e2 –generate-cli-skeleton

Edit the file to your needs or liking:

vi cr_img.json
{
“DryRun”: false,
“InstanceId”: “i-050357e3ecce863e2”,
“Name”: “OL73 UEKR3 LVM”,
“Description”: “OL73 UEKR3 LVM 10GB disk with swap and root on LVM thus expandable”,
“NoReboot”: true
}

And create the AMI:

aws ec2 create-image –cli-input-json file:///home/ec2-user/cr_img.json
{
“ImageId”: “ami-27637b41”
}

It takes a few minutes for the AMI to be visable in the webconsole of AWS EC2.

Don’t forget to:

  • Deregister the AMI generated bij VMImport
  • Delete the corresponding snaphot
  • Terminate the instance you used to create the new AMI
  • Delete the volumes of that instance (if they are not deleted on termination) (expand the info box in AWS you see when you terminate the instance to see which volume it is. E.g.: The following volumes are not set to delete on termination: vol-0150ca9702ea0fa00)
  • Remove the OVA from your S3 bucket if you don’t need it for something else.

Launch an instance of your new AMI and start to use it.
