Description

This repository contains scripts that makes it easy to start working on random projects without installing a bunch of dependencies on the host computer.

generate .env

.assets/gen_env.sh

build

docker compose build

create network if it doesn't exist yet

bash -c '. .env; docker network ls --format "{{.Name}}" | grep -Fxq "${NETWORK_NAME}" || docker network create "${NETWORK_NAME}"'

start the container

docker compose up -d

SSH

By default password is equal to username. You can change it, or remove it and use ssh key.

ssh to the container

.assets/ssh.sh

other ways to ssh

using network_mode: host

This one might be the most convenient, especially if you need to run some services on localhost, but want to access them from the host machine. It might be a bit annoying to deal with port conflicts.

Uncomment network_mode: host and add the following to dockerfile_inline:

RUN echo 'Port 2022' >> /etc/ssh/sshd_config

Add the following to your ssh config (example):

Host devbox_test-devbox-1
    Hostname localhost
    Port 2022

Run docker compose up -d --build and then ssh:

ssh devbox_test-devbox-1

using hoster

dvddarias/docker-hoster will insert container name in /etc/hosts so you can ssh <containername> which is handy, just run docker ps -a to get container name first.

using dnsdock with dnsmasq

aacebedo/dnsdock provides DNS resolution.

Start the following

docker run --restart=unless-stopped -d -v /var/run/docker.sock:/var/run/docker.sock --name dnsdock -p 127.0.1.53:53:53/udp aacebedo/dnsdock:v1.17.0-amd64 -v --domain=docker

Add the following to /etc/dnsmasq.conf

server=/docker/127.0.1.53

Then you can add to ssh config (example):

Host devbox_test-devbox-1
    Hostname devbox_devbox_test.docker

Then ssh:

ssh devbox_test-devbox-1

ssh to devcontainer on another machine

You can uncomment ports section and ~/.Xauthority section in docker-compose.yml and do the following

ssh -Y -p 2022 $USER@<hostmachine>
