Consolidated devcontainer configs as VPS-like server

• This repo contains working configs that can be used to spin up a server-like environment in your local machine.
• What can you do with it?
  • Isolate development projects as separate containers (think filesystem, environment vars, running process etc.)
  • Create docker containers inside the container itself, (utilizing docker-in-docker under the hood)
  • Use vs code to SSH to the container like a normal server

• More info on devcontainers here

prequisite

• devcontainer cli npm install -g @devcontainers/cli
• docker

scaffold the devcontainer

• use followg command to clone & rename the dir to devcontainer_prod which gets referred in the scripts (no need to cd to the repo after cloning) git clone https://github.com/luutuankiet/devcontainer_prod.git devcontainer_prod
• open config at devcontainer_prod/devcontainer.json and make changes for features i.e.

	"features": {
		"ghcr.io/devcontainers/features/node:1": {
			"nodeGypDependencies": true,
			"installYarnUsingApt": true,
			"version": "lts",
			"nvmVersion": "latest"
		},
		"ghcr.io/devcontainers/features/sshd:1": {
			"version": "latest"
		}
    }

• change various container runtime environment per your requirment, e.g

  • change the name and add some ports to forward. Recommended at least one port if you plan to use the ssh feature later on

   	"runArgs": [
   		"--name",
   		"PROD_gtd_ETL",
   		"-p=60000:60000", // ssh
   		"-p=60001:60001" // dagster
   	]

  • change persistent env variable in containerEnv
  • full list of params and args in devcontainer doc

• copy postCreateCommand_example.sh to postCreateCommand.sh and make changes per your requirement. recommended to keep sections python and zsh setups

• spin up the devcontainer. By default --workspace-folder is required which will bind mount current dir to container's /workspace dir

• run devcontainer up --config devcontainer_prod/devcontainer.json --workspace-folder . (add --remove-existing-container if you want to rebuild)

• clone the repo and unpack to the workspace

ssh setup

(sshd feature guide.)

• requires this devcontainer config block

		"ghcr.io/devcontainers/features/sshd:1": {
			"version": "latest"
		}

• wait for devcontainer successfully spins up then attach shell to it with docker exec -it PROD_gtd_ETL /bin/bash (PROD_gtd_ETL be the container name defined earlier)
• passwd and change the root password
• vim /etc/ssh/sshd.config and update the port value to the desired port e.g. 60000
• /etc/init.d/ssh restart to restart the ssh server
• ssh -p 60000 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o GlobalKnownHostsFile=/dev/null root@<machine_ip>k
