making user-based development environment on linux with docker

1. Mounting user home folder (if using host_script)
   • User can use their home folder in container
2. PID 1 is init process (if using host_script)
3. Handling user with gosu
   • file in container home folder have same owner as host (initial password in container is snip)
   • you can read/write file as same user of host
4. You just build gosu docker file after your develop environment docker image

1. Change base image of gosu/Dockerfile which you need
2. Build gosu directory with docker build -t gosu ./gosu
3. run container with script (user_script/docker_run.sh)

• docker_run: sudo docker_run.sh "image" "container-name-you-want'
• docker_exec: sudo docker_exec.sh "container" "command"

1. add user or group to sudoers (Make this users only able to run docker_* with sudo)
   • This is for limit permission of added user.
2. Build gosu directory with docker build -t gosu ./gosu for default image
3. Use base directory for install essential packages if you need
