odoo-v8-nightly-docker

Overview

We created a self-contained [Odoo 8.0 Docker image]
(https://registry.hub.docker.com/u/yingliu4203/odoo8nightly/) that
is based on [the latest Odoo 8.0 nightly build]
(http://nightly.openerp.com/8.0/nightly/deb/).
The Dockerfile code is in [a GitHub repository]
(https://github.com/YingLiu4203/odoo-v8-nightly-docker). It is based on
[Shaker Qawasmi's Odoo Dockerfile]
(https://github.com/sqawasmi/odoo-docker/blob/v8/Dockerfile)
and uses some scripting ideas from
[ANDRÉ SCHENKELS's Odoo installation script]
(https://github.com/aschenkels-ictstudio/openerp-install-scripts/blob/master/odoo-v8/ubuntu-14-04/odoo_install.sh).
There are three major changes from other Odoo images:

  • It uses the recently available Odoo 8.0 nightly build
  • It is self-contained. We use a local postgresql database that
    comes with the Odoo 8.0 installation.
  • It does not use extra configuration files. All configuration files
    are created using Dockerfile code.

To Use It

Run the following command in a machine that has Docker installed.

sudo docker run --name odoo8 -p 2222:22 -p 5432:5432 -p 8069:8069 -d yingliu4203/odoo8nightly

The above command creates a Docker instance named "odoo8" from the
Docker image. If not for a Docker bug, this command is all you need.
However, there is a "Permission denied" Postgresql error when
you run an image that was built in Docker Hub. To fix it,
you need to login to the container. There are two methods:

# If you use Docker 1.3 or newer, you can use the following command to login:

sudo docker exec -it odoo8 bash

### If you use Docker 1.2 or older, you need a tool 
called [nsenter](https://github.com/jpetazzo/nsenter).  
The following command installs nsenter into /usr/local/bin
and login to the container ###

# sudo docker run --rm -v /usr/local/bin:/target jpetazzo/nsenter

# sudo docker-enter odoo8

# Inside the container, change the owner of a Postgresql directory.
chown postgres:postgres -R /var/lib/postgresql/9.3/main/

# exit the container

exit

After the above fix, all services are in good standing. Just type
"http://your-host-ip:8069" in your browser and enjoy.

To stop it:

sudo docker stop odoo8

To restart it:

sudo docker start odoo8

The created Docker container exposes SSH (from 22 to 2222),
Postgresql (5432) and Odoo (8069) ports in the host.
You can connect to these services remotely.To use SSH,
you need to config user and password in the container.

In the container, you can stop Postgresql or Odoo service
by finding their process id and kill them.
Then you can start the services using the init.d service command

/etc/init.d/postgresql start
/etc/init.d/openerp start

Technical issues

The [Docker build file]
(https://github.com/YingLiu4203/odoo-v8-nightly-docker/blob/master/Dockerfile)
looks simple. However, there were some technical issues in creating
this file. We document them here thinking that somebody may want
to fork and customize it.

  • Set locale. Otherwise, Postgresql and Odoo may use different locale.
  • Make /var/run/sshd directory. Otherwise, SSH may not run.
  • Set "ssl=false" in Postgresql configuration to fix another Docker bug.
  • Run all services in interactive mode using Supervisor.
    A service starts/stops when a container starts/stops. If you want,
    you can kill any service and re-start it inside a container.
  • Create home directory for openerp user. Odoo creates this
    account but doesn't create the home directory.
  • Set "HOME" environment variable for openerp user. Odoo may
    complain if it is not there.
  • Use CMD, not ENTTRYPOINT, to run supervisord
  • Even I put chown postgres:postgres -R /var/lib/postgresql/9.3/main/
    into the Dockerfile, the downloaded image still has wrong owner for
    base/ directory.

The tricky thing is that some issues, such as the Postgresql directory
ownership bug, only occur when you image is built by Docker Hub.
