dvladnik/postgres-ebs repository overview

⁠Postgres container with EBS auto-mount

• latest (Dockerfile)⁠

docker run -d --privileged -v /etc/ecs:/ecs sdvladnik/postgres-ebs

How it works:

1. Finds available EBS volume with tag Name=$ECS_CLUSTER-$CONTAINER;
2. Finds free device name and attaches EBS to host machine as a new device;
3. Mounts volume directly into Docker container and starts Postgres database;
4. Intercepts container stop command, unmounts and detaches EBS volume and makes it available for other container to use

Requires additional instance role permissions and privileged mode:

• ec2:AttachVolume
• ec2:DetachVolume
• ec2:DescribeVolumes
