AWS CLI on CoreOS
No, you can't install
aws-cli on CoreOS.
Yes, you can run this container and call out to it.
I wanted to pull container images from my Elastic Container Registry (ECR) into my CoreOS on EC2, but in an automated way.
- Sure I could do it manually just fine.
- I wanted to do it automatically.
- AWS documentation offered no obvious solution beyond "use ECS" which has its own share of problems.
Run a container within CoreOS that has the aws cli tools installed, and simply mount a volume from CoreOS that contains the necessary configuration. Run commands from within that.
Build the container
docker build -t aws/cli .
~/.aws/credentials exist in your CoreOS instance.
[default] region = us-east-1
[default] aws_access_key_id = AKIXXXXXXXXXXXXXXXXX aws_secret_access_key = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Run your commands within the container
docker run -it -v $HOME/.aws:/home/aws/.aws aws/cli <command> <args>
docker run -it -v $HOME/.aws:/home/aws/.aws aws/cli aws s3 ls
Get ECR Login
docker run -it -v $HOME/.aws:/home/aws/.aws aws/cli aws ecr get-login
Use a named profile
run -it -v $HOME/.aws:/home/aws/.aws aws/cli aws ecr get-login --profile groove
