Compose V2

SeaweedFS now uses the v2 syntax docker compose

If you rely on using Docker Compose as docker-compose (with a hyphen), you can set up Compose V2 to act as a drop-in replacement of the previous docker-compose. Refer to the Installing Compose section for detailed instructions on upgrading.

Confirm your system has docker compose v2 with a version check

bash

$ docker compose version
Docker Compose version v2.10.2

Try it out

bash


wget https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/seaweedfs-compose.yml

docker compose -f seaweedfs-compose.yml -p seaweedfs up

Try latest tip

bash


wget https://raw.githubusercontent.com/seaweedfs/seaweedfs/master/docker/seaweedfs-dev-compose.yml

docker compose -f seaweedfs-dev-compose.yml -p seaweedfs up

Verify an image signature

Every image CI pushes to chrislusf/seaweedfs and ghcr.io/chrislusf/seaweedfs is signed with cosign, keyless, by the GitHub Actions workflow that built it, so there is no key to fetch or pin. The signature is attached to the image digest and covers the multi-arch index and each platform image in it; latest is the release image under another tag and verifies the same way. Images published before September 2026 predate signing.

bash

cosign verify \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com \
  --certificate-identity-regexp '^https://github.com/seaweedfs/seaweedfs/\.github/workflows/container_release_unified\.yml@' \
  chrislusf/seaweedfs:latest

cosign prints the digest it verified. Deploy by that digest, or let an admission controller resolve the tag, so what runs is what was checked.

The identity is https://github.com/seaweedfs/seaweedfs/.github/workflows/<workflow>@<ref>. The ref is refs/tags/<version> for a release and refs/heads/master when a variant was republished by hand. The workflow is container_release_unified.yml for the release images, container_dev.yml for dev, container_latest.yml for a latest rebuilt by hand, container_release_foundationdb.yml for the _large_disk_foundationdb release image, and container_foundationdb_version.yml or container_rocksdb_version.yml for the per-version builds. The regexp above accepts release images only; container_[a-z_]+\.yml@ accepts everything this repository publishes, dev included.

The same check as a Kyverno policy, release images only:

Local Development

bash

cd $GOPATH/src/github.com/seaweedfs/seaweedfs/docker
make

S3 cmd

list

s3cmd --no-ssl --host=127.0.0.1:8333 ls s3://

Build and push a multiarch build

Make sure that docker buildx is supported (might be an experimental docker feature)

bash

BUILDER=$(docker buildx create --driver docker-container --use)
docker buildx build --pull --push --platform linux/386,linux/amd64,linux/arm64,linux/arm/v7,linux/arm/v6 . -t chrislusf/seaweedfs
docker buildx stop $BUILDER
