This is a quick tutorial on setting up a Redmine on Docker container.
Overview
Redmine is a flexible project management web application written using Ruby on Rails framework.
Architecture
This is to simulate how to dockerize a production-ready infrastructure on Redmine application using Nginx as reverse proxy.
Prerequisite
I'm using the Multipass to setup my docker platform.
PS> multipass launch docker -n dido
PS> multipass shell dido
Setup
First, create 3 files within an empty folder.
- Dockerfile
- conf/default.conf
- conf/supervisord.conf
~$ mkdir red
~$ cd red
~/red$ cat Dockerfile
------------------8<-------------------------
FROM redmine:5
RUN apt update && \
apt install -y \
supervisor \
nginx && \
apt clean && \
rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
COPY conf/supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY conf/default.conf /etc/nginx/sites-available/default
EXPOSE 80
ENTRYPOINT ["/usr/bin/supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]
------------------8<-------------------------
~/red$ cat conf/default.conf
------------------8<-------------------------
server {
listen 80;
server_name _;
location / {
proxy_pass http://127.0.0.1:3000;
}
}
------------------8<-------------------------
~/red$ cat conf/supervisord.conf
------------------8<-------------------------
[supervisord]
nodaemon=true
user=root
[program:nginx]
user=root
command=nginx
[program:redmine]
user=redmine
directory=/usr/src/redmine
command=/docker-entrypoint.sh rails server -b 127.0.0.1
------------------8<-------------------------
Build the Docker Image
Next, build the docker image called "redapp".
~/red$ docker build -t redapp .
Sending build context to Docker daemon 4.608kB

Successfully built 3e9b0eecdfaf
Successfully tagged redapp:latest
Start the Docker image as Container
Next, run the container by exposing the port 80 (external on eth0 interface) with Nginx (internal port 80 on docker0 interface)
~/red$ docker run -p 80:80 -d redapp

Access the Redmine Application
Last, point the browser to the URL at http://172.18.238.107/login (where 172.18.238.107 is the IP address at my eth0 interface).
