molindo-ecs2-base

AMI built on top of the Amazon Linux 2 ECS AMI for use in an autoscaling ECS instance cluster.

  • available as molindo-ecs2-base-{{timestamp}}
  • available in us-east-1, eu-west-1, eu-central-1

Variables

variables are set in /etc/profile.d/01-ec2-env.sh and written by update-ec2-env.sh during startup (after cloud-init).

  • EC2_REGION
  • EC2_INSTANCE_ID
  • EC2_VPC_ID
  • AWS_DEFAULT_REGION (for aws-cli)
  • EC2_ELASTIC_IP

Scripts

  • ec2-instances.sh - get a list of EC2 instances in this TIM environment
  • ec2-tag.sh - get an instance tag value
  • ephemeral-fstab.sh - write an /etc/fstab entry for an ephemeral volume
  • ebs-fstab.sh - write an /etc/fstab entry for an EBS volume
  • efs-fstab.sh - write an /etc/fstab entry for an EFS volume

Configuration

Configuration can be done by running commands using EC2 user data, e.g.

Content-Type: text/cloud-config

bootcmd:
 - [ /usr/bin/cloud-init-per, once, ephemeral_fstab, /usr/local/bin/ephemeral-fstab.sh, /mnt/ephemeral, ext4 ]

mounts:
 - [ swap, null ]

swap:
   filename: /swap.img
   size: auto
   maxsize: 8G

Note that cloud-init will run as part of systemd startup and therefore running systemctl may lead to deadlocked startup.
