2. source code: github
3. docs: docker-systemd-docs

what's it

1. docker image of centos with systemd
2. bind with sshd
3. mainly used for testing environment construction

limitations

1. only supporting amd64 and arm64
2. only supporting centos7 and centos8 as base image
3. "UseDNS no" written to /etc/ssh/sshd_config

todo list

1. add test scripts for sshd

usage

1. requirements
   • system os and arch
     • linux & amd64 (tested with centos 7)
     • linux & arm64 (not tested, but it will be okay)
     • mac & amd64 (not tested, but it will be okay)
     • mac & arm64 (tested with mac mini whose chip is apple m1)
     • windows & x86_64 (not tested, but it will be okay)
   • jdk 8 or higher to run gradle scripts
   • docker to build/run service
2. start service
   • build docker image
     • optional

     • ./gradlew :buildDockerImage

   • run docker container

     • ./gradlew :runDockerContainer

     • ssh service will be exposed with port 1022
3. test service
   • TODO
4. stop service

   • ./gradlew :stopDockerContainer

5. you can also jump into the container with ssh

   • ssh -o "UserKnownHostsFile /dev/null" -p 1022 root@localhost

6. build multi-platform images and push them to docker registry

   • ./gradlew :pushDockerImage

   • you need an environment to build multi-platform images: develop with docker
