常用示例
Pull an image
docker image pull [image]
Pull specific tag
docker image pull [image]:[tag]
Pull all tags
docker image pull -a [image]
Pull by digest
docker image pull [image]@[sha256:digest]
Pull for a specific platform
docker image pull --platform [linux/arm64] [image]:[tag]
Pull from specific registry
docker image pull [registry.example.com/image]:[tag]
说明
docker image pull downloads a Docker image or repository from a registry to the local Docker daemon. When no registry is specified, Docker Hub serves as the default source. If no tag is provided, the latest tag is assumed. The pull operation downloads image layers in parallel for efficiency. If some layers already exist locally from other images, Docker reuses them through its content-addressable storage system, minimizing bandwidth and storage requirements. Images can be pulled by tag for version-specific deployments or by SHA256 digest for immutable, verifiable image references. The --platform flag enables pulling multi-architecture images for cross-platform development and deployment scenarios.
