# Docker and YunoHost
|
|
|
|
*Here is a small memo-documentation page on how to test/develop YunoHost with Docker.*
|
|
|
|
*Find other ways to install YunoHost **[here](/install)**.*

|
|
## Install Docker
|
|
|
|
**Pre-requisite**: a x86 computer under Ubuntu 14.04 (or above), or ArchLinux.
|
|
|
|
On Ubuntu :
|
|
```bash
|
|
curl -s https://get.docker.io/ubuntu/ | sudo sh
|
|
```
|
|
|
|
On ArchLinux :
|
|
```bash
|
|
sudo pacman -Sy docker
|
|
```
|
|
|
|
**Note:** you may have to start Docker's daemon manually (as root: `service docker start`, `systemctl start docker` or simply `docker -d`)
|
|
|
|
---
|
|
|
|
## Build the YunoHost container
|
|
|
|
The following command will fetch the latest YunoHost built image:
|
|
```bash
|
|
docker pull zamentur/yunohost-stable8
|
|
```
|
|
|
|
You can also build the image manually:
|
|
```bash
|
|
docker build -t zamentur/yunohost-stable8 github.com/YunoHost/Dockerfile
|
|
```
|
|
|
|
You can check that the container is successfully built with the `docker images` command.
|
|
|
|
---
|
|
|
|
## Run the container
|
|
To start the container, run the next command by replacing DOMAIN by a valid domain e.g.: example.com => yunohost.example.com
|
|
```bash
|
|
docker run -h yunohost.DOMAIN -v $(pwd):/yunohost -d zamentur/yunohost-stable8 /sbin/init
|
|
```
|
|
|
|
If you want to run the container and forward all the interesting ports to the host:
|
|
|
|
```bash
|
|
docker run -d -h yunohost.DOMAIN -v $(pwd):/yunohost \
|
|
-p 25:25 \
|
|
-p 53:53/udp \
|
|
-p 80:80 \
|
|
-p 443:443 \
|
|
-p 465:465 \
|
|
-p 993:993 \
|
|
-p 5222:5222 \
|
|
-p 5269:5269 \
|
|
-p 5290:5290 \
|
|
zamentur/yunohost-stable8 \
|
|
/sbin/init
|
|
```
|
|
|
|
You can find more information on these steps on the Docker's documentation:
|
|
* http://docs.docker.com/reference/commandline/cli/#run
|
|
* http://docs.docker.com/userguide/dockerlinks/

|
## Post-installation
|
|
Go in the container by replacing XXXX by the id obtained when `docker run`
|
|
```bash
|
|
docker exec -t -i XXXX /bin/bash
|
|
```
|
|
Next run postinstall with the dedicated script to docker
|
|
```bash
|
|
postinstall
|
|
```
|

## Useful commands
|
|
|
|
|
|
Find your container's IP address (should looks like 172.17.0.x)
|
|
|
|
```bash
|
|
docker inspect --format '{{ .NetworkSettings.IPAddress }}' <CONTAINER_ID>
|
|
```
|
|
|
|
|
|
Snapshot container's state
|
|
|
|
```bash
|
|
docker commit <container_ID> zamentur/yunohost-stable8:tag
|
|
# E.g.: docker commit 3e85317430db zamentur/yunohost-stable8:03052014
|
|
```
|
|
|
|
Assign an IP to a container
|
|
|
|
```bash
|
|
# You will need iptables, and to activate IP forwarding on your system
|
|
iptables -t nat -A PREROUTING -d <IP.to.assign> -j DNAT --to-destination <container.IP>
|
|
iptables -t nat -A POSTROUTING -s '<container.IP>/32' -o eth0 -j SNAT --to-source <IP.to.assign>
|
|
# Be careful on the network interface (here eth0)
|
|
```
|
|
|
|
Log in a YunoHost running container
|
|
|
|
```bash
|
|
# Otherwise, with docker
|
|
docker exec -t -i <container_ID> /bin/bash
|
|
```
