Login tool for AWS Container Registry.
This is a lightweight golang version of the AWS command-line utility
aws ecr get-login, designed to build into a small scratch docker
image.
Can also produce output in other formats using golang templates.
See build or docker image below.
Login to your AWS Container Registry:
$ eval $(./ecr-login)
WARNING: login credentials saved in /Users/ric/.docker/config.json
Login Succeeded
Alternatively, you can use the included templates to output docker
config format directly and redirect output to ~/.docker/config.json
or ~/.dockercfg:
$ TEMPLATE=templates/config.tmpl ./ecr-login
{
"auths": {
"https://1234567890.dkr.ecr.us-east-1.amazonaws.com": {
"auth": "...",
"email": "none"
}
}
}
This is an example of how I use ecr-login with systemd units on
