The quay.io/minio/minio and quay.io/minio/mc images now answer 401, and
the minio images are gone from Docker Hub as well: the dev stack, the
backend CI job and the helm dev-backend could not pull them anymore.
[pgsty/silo](https://hub.docker.com/r/pgsty/silo) and
[pgsty/mc](https://hub.docker.com/r/pgsty/mc) are community builds and drop
in replacement of minio. Only the executable name is changing from minio
to silo.
We need to use valkey instead of an old redis version. We decided to use
the operator https://github.com/chideat/valkey-operator/ and configure
it in both feature and dev environments.
MinIO stopped publishing images on Docker Hub in October 2025 and
archived its GitHub repository in February 2026. `minio/mc` and
`minio/minio` can no longer be pulled, so the `createbuckets` service
fails with `pull access denied for minio/mc`. The same images are still
served from quay.io.
