A rootless container running https://mogeko.github.io/docker-vlmcsd/vlmcsd.8.pdf.

Since March 2023, vlmcsd images has been upgraded to a rootless container, it based on https://github.com/GoogleContainerTools/distroless and uses Buildah as a container compilation engine. Why do we use them?.

Usage

Pull this image:

shell
docker pull mogeko/vlmcsd:latest

Run with docker cli:

shell
docker run -d --name vlmcsd -p 1688:1688 --restart unless-stopped ghcr.io/mogeko/vlmcsd:latest

Run with docker-compose:

yml
---
version: 2.1
services:
  vlmcsd:
    image: mogeko/vlmcsd:latest
    container_name: vlmcsd
    ports:
      - 1688:1688
    restart: unless-stopped

Parameter

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

About "Distroless" images and Buildah

https://github.com/GoogleContainerTools/distroless is an application-centered OCI container image launched by Google for the Kubernetes project. It contain only your application and its runtime dependencies. They do NOT contain package managers, shells or any other programs you would expect to find in a standard Linux distribution (Your application will be the only executable program in the entire container image).

Compared with the traditional complete https://hub.docker.com/_/debian container image, Distroless has an unparalleled _size advantage, its https://github.com/GoogleContainerTools/distroless/blob/main/base/README.md is only 2MB, less than 2% of the Debian (124MB). Compared with https://hub.docker.com/_/alpine, it has a smaller *** surface and better compatibility (based on Debian and glibc).

As for Buildah. It is a container mirror compilation engine launched by Red Hat. Its biggest selling point is that it allows you to create a container images in a completely unprivileged environment, that is "rootless". With the help of Buildah, we were able to put the entire life cycle of the container's compilation and operation in the user namespace. So as to protect our digital security.
