It lets Docker fetch ECR authentication through AWS credentials instead of requiring users or automation to run docker login for ECR registries. ### Project history The project is maintained under awslabs and implements Docker's credential-helper protocol as docker-credential-ecr-login. Its README describes the helper as a bridge between Docker, Amazon ECR, and the normal AWS credential chain, including shared credentials files, environment variables, EC2 and ECS roles, assumed roles, credential_process, and web identity support. The changelog shows an initial 0.1.0 release in 2018, followed by endpoint and credential-chain work: FIPS endpoints in 0.2.0, PrivateLink endpoints in 0.3.0, assumed-role chaining and IRSA support in 0.4.0, ECR Public and IMDSv2 support in 0.5.0, AWS SSO and Apple Silicon support in 0.6.0, and later support for isolated, IPv6, and dual-stack ECR endpoint patterns. ### Adoption history The README documents installation paths across Amazon Linux, Debian, Ubuntu, Arch, Alpine, macOS Homebrew, MacPorts, Windows releases, mise, and Go source installs. That distribution spread reflects its role as a small but standard glue package for CI systems, developer laptops, and hosts that pull private ECR images. ### How it is used Users place docker-credential-ecr-login on PATH and set Docker's credsStore or per-registry credHelpers entry to ecr-login. After that, docker pull and docker push against private or public ECR registries use AWS credentials automatically, with optional AWS_PROFILE selection and local helper cache controls. ### Why package nerds care For package maintainers, this package is interesting because it connects three packaging worlds: Docker's external credential-helper interface, AWS's credential provider chain, and distro or language package managers. A broken helper can make otherwise-correct Docker and AWS installs unable to pull private images, so version and path details matter. ### Timeline - 2018: v0.1.0 tagged as the initial release. - 2019: Debian and Amazon Linux packaging tags appear in the upstream repository. - 2021: v0.5.0 adds ECR Public and IMDSv2 support. - 2021: v0.6.0 adds AWS SSO, EC2 metadata role assumption, and Apple Silicon support. - 2024: v0.8.0 adds C2S endpoint pattern support and experimental Windows ARM binaries. - 2026: v0.12.0 adds dual-stack ECR public endpoint support and SHA256 cache keys. ### Related projects - The project is directly related to Docker's docker-credential-helpers suite, Amazon ECR, the AWS CLI and SDK credential chain, Amazon ECS and EC2 IAM roles, and Kubernetes IRSA workflows. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
