Docker Compose With Coder: How to

Config

The default configuration is located in the .env file. I'm working on a arm64 architecture. So, ff you need to adapt the values of the environment variables, create an new env file (ex: amd64.env) and use the --env-file flag of Docker Compose.

  • Add .config to .gitignore

Build

docker compose --env-file .env build

Run

# If you use .env
docker compose up -d
# If you use a specific .env file
docker compose --env-file ./amd64.env up  -d

Then:

  • Open: http://0.0.0.0:4000
  • Open a terminal from the Web IDE
  • Type this command git config --global --add safe.directory /ide.simplism.cloud
  • And configure git (if necessary): 
    git config --global user.name @your-handle
git config --global user.email [email protected]

Connect to the container

set -o allexport; source .env; set +o allexport
docker exec --workdir /${WORKDIR} -it ${CONTAINER_NAME} \
/bin/bash

Stop

docker compose down

Docker in Docker

If you get this error message: permission denied while trying to connect to the Docker daemon socket, use this before : sudo chmod 666 /var/run/docker.sock.

TLS certificates

Use TLS certificates

Update the .env file with the name of the certificate and the key:

For example:

TLS_CERT=ide.simplism.cloud.crt
TLS_CERT_KEY=ide.simplism.cloud.key
  • Copy the certificate and the key to the ./certs folder
  • Give the appropriates rights to the files: chmod 777 ide.simplism.cloud.*
  • Add this to your hosts file: 0.0.0.0 ide.simplism.cloud
  • Use this entrypoint in the compose.yaml file: entrypoint: ["code-server", "--cert", "/${WORKDIR}/certs/${TLS_CERT}", "--cert-key", "/${WORKDIR}/certs/${TLS_CERT_KEY}", "--auth", "none", "--host", "0.0.0.0", "--port", "${CODER_HTTP_PORT}", "/${WORKDIR}"]
  • Restart: docker compose up

open https://ide.simplism.cloud:4000

Use Mkcert

First install mkcert (https://github.com/FiloSottile/mkcert?tab=readme-ov-file#installation) Then:

cd certs
mkcert -key-file ide.personal.faas.key -cert-file ide.personal.faas.crt personal.faas "*.personal.faas"
mkcert -install
chmod 777 ide.personal.faas.*
  • Update the .env file with the name of the certificate and the key
  • Add this to the hosts file: 0.0.0.0 ide.personal.faas
  • Use this entrypoint in the compose.yaml file: entrypoint: ["code-server", "--cert", "/${WORKDIR}/certs/${TLS_CERT}", "--cert-key", "/${WORKDIR}/certs/${TLS_CERT_KEY}", "--auth", "none", "--host", "0.0.0.0", "--port", "${CODER_HTTP_PORT}", "/${WORKDIR}"]
  • Restart: docker compose up

open https://ide.personal.faas:4000
