Scalable Self-Hosted GitHub Runners on AWS Cloud
The naming convention and tagging standards used for the ECR runner image(s) repositories are site-specific. To keep things simple, the assumption is we are planning for on a single runner type—Debian Linux, x64 architecture.
Create an ECR private repository github-actions-self-hosted-runner-debian:
aws --profile admin_profile ecr create-repository \
--repository-name github-actions-self-hosted-runner-debian \
--region us-east-1Sample output:
{
"repository": {
"repositoryArn": "arn:aws:ecr:us-east-1:xxxxxxxxxxxx:repository/github-actions-self-hosted-runner-debian",
"registryId": "xxxxxxxxxxxx",
"repositoryName": "github-actions-self-hosted-runner-debian",
"repositoryUri": "xxxxxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/github-actions-self-hosted-runner-debian",
"createdAt": "2023-01-07T05:31:56+00:00",
"imageTagMutability": "MUTABLE",
"imageScanningConfiguration": {
"scanOnPush": false
},
"encryptionConfiguration": {
"encryptionType": "AES256"
}
}
}From the above, the repository URI is: xxxxxxxxxxxx.dkr.ecr.us-east-1.amazonaws.com/github-actions-self-hosted-runner-debian.
