MinIO in Docker

MinIO in Docker

Running MinIO in Docker on This Host

With no community images left, you build your own: clone the last release tag, make build, and copy the Go binaries into a slim image whose six-line Dockerfile (in demos/ch08/minio/) starts FROM debian:trixie-slim, copies minio and mc to /usr/local/bin, and sets CMD ["server", "/data/disk{1...4}", "--console-address", ":9001"].

build.sh: clone, compile and package the last AGPLv3 releaseShell

# Build the last AGPLv3 MinIO release and its mc client from source (needs Go 1.24+, Docker).
clone() {   # retried: this host's network drops TLS sessions now and then
  for i in $(seq 10); do
    git -c advice.detachedHead=false clone -q --depth 1 --branch "$@" && return; sleep 5; done; }

The compile takes about two minutes with Go 1.26.0; MINIO_RELEASE=RELEASE stamps the release name in. The CMD's /data/disk{1...4} is MinIO 30,943 's own expansion, giving one container a four-drive erasure set. Start it on the l1-lake network that the catalog and Trino 403,499 join later:

run_minio.sh: start l1-minio and register it with mcShell

# Start MinIO: four drives in one erasure set, S3 API on port 31900, console on 31901.

Added `lake` successfully.
The cluster 'lake' is ready

The server idles at about 62 MiB; its root credentials suit a local sandbox only (Security and Lakehouse Costs).
