🐳 🐙 Docker Compose Tip #93
An app connects to localhost:6379, but Redis never lives in the same place twice across dev/staging/prod. The ambassador pattern puts that difference in one disposable proxy, not app code.

@lours.me🐳 🐙 Docker Compose Tip #91
A provider used to push to a registry or shell out to docker save by hand to get bytes to a remote runtime. Compose 5.6.0 lets it opt into the same image phase and request them directly.

AI agents write mediocre Dockerfiles: latest tags, no health checks, root left in place. docker/skills fixes that: 11 SKILL.md guides across Build, Compose, Sandboxes, Agent.

docker compose alpha viz turns depends_on into a Graphviz graph. Pipe into dot -Tpng and any Compose file becomes a picture.
Still alpha since April 2023, no graduation date yet.
@lours.me🐳 🐙 Docker Compose Tip #89
cap_drop: ALL doesn't just fence in non-root users, it takes CHOWN away from root (uid 0) too.
Gotcha: the classic "drop NET_RAW, ping breaks" demo often does nothing on modern hosts.
@hugovalters.bsky.socialSomeone told you to run docker swarm init on a single VPS. That was a cargo cult. Here's how to rip out Swarm and switch to Docker Compose the right way. https://www.valtersit.com/guides/docker/docker-swarm-is-dead-long-live-compose/ #docker #devops #compose
@lours.me🐳 🐙 Docker Compose Tip #88
docker compose alpha generate creates a Compose file from running containers. Still alpha: skip a host IP on a published port and it writes host_ip: invalid IP
A real bug, and an easy first PR.

@lours.me🐳 🐙 Docker Compose Tip #87
depends_on has more than service_healthy: wait for a one-shot with service_completed_successfully, cascade restarts with restart: true, or soften it with required: false.
@lours.me🐳 🐙 Docker Compose Tip #86
Meet initial_sync, the watch attribute for catching up a running stack.
5.5.1: every file now syncs, Dockerfiles stay out, symlinks don't break it.

See what's incubating: docker compose alpha is where new commands land before going stable.
Right now: viz (dependency graphs) and generate (reverse a Compose file from running containers).
@lours.me🐳 🐙 Docker Compose Tip #84
A failing post_start / pre_stop / pre_start hook used to report only:
db hook exited with status 1
Since Compose 5.5.1, its output travels with the error too.
