docker compose up: what it does, flag by flag
What docker compose up decides for each service on every run, and how --wait, --build, --pull and --remove-orphans behave when a script or CI job runs it.
Install Docker on Rocky Linux or AlmaLinux
Install Docker Engine on Rocky Linux or AlmaLinux with dnf, then fix what Ubuntu guides skip: podman owning the docker command and SELinux on bind mounts.
Docker Compose command vs entrypoint
ENTRYPOINT is what runs and command supplies its arguments. See all four override combinations in Compose, and why setting entrypoint clears CMD.
Docker Compose exec: get an interactive shell
Open a shell in a running Compose service with docker compose exec, and use run --rm for a service that is stopped or must not be disturbed.
FreeBSD jails vs Docker containers
Jails isolate a full FreeBSD userland; Docker ships layered images from a registry. How the two models differ on software, state, networking and limits.
Is Docker Compose deprecated?
The Python docker-compose reached end of life. The docker compose plugin did not, and it still ships releases. Here is what your server actually runs.
Podman vs Docker on a VPS: what really differs
Podman runs containers with no daemon and rootless by default. What that changes on a rented server: compose files, quadlets, ports and volume ownership.
Docker Compose TZ: fix container time
Set TZ in a Compose service, find valid zone names with timedatectl, and understand why container logs show UTC while the host clock is right.
Run just one service with Docker Compose
Update one container in a multi-service stack: docker compose up -d web, why depends_on still starts, --no-deps, start vs up, stop, and --scale.
Restart or rebuild a Docker Compose service
Restart, up -d, rebuild or pull: which Docker Compose command picks up an edited compose file, a new .env, a changed Dockerfile or a new image.
