Full Description

Huginn for docker with multiple container linkage

This image runs a linkable Huginn instance.

There is an automated build repository on docker hub for cantino/huginn.

This was patterned after sameersbn/gitlab by ianblenke/huginn, and imported here for official generation of a docker hub auto-build image.

The scripts/init script generates a .env file containing the variables as passed as per normal Huginn documentation.
The same environment variables that would be used for Heroku PaaS deployment are used by this script.

The scripts/init script is aware of mysql and postgres linked containers through the environment variables:

MYSQL_PORT_3306_TCP_ADDR
MYSQL_PORT_3306_TCP_PORT

and

POSTGRESQL_PORT_5432_TCP_ADDR
POSTGRESQL_PORT_5432_TCP_PORT

Its recommended to use an image that allows you to create a database via environmental variables at docker run, like paintedfox / postgresql or centurylink / mysql, so the db is populated when this script runs.

If you do not link a database container, a built-in mysql database will be started.
There is an exported docker volume of /var/lib/mysql to allow persistence of that mysql database.

Additionally, the database variables may be overridden from the above as per the standard Huginn documentation:

HUGINN_DATABASE_ADAPTER #(must be either 'postgres' or 'mysql2')
HUGINN_DATABASE_HOST
HUGINN_DATABASE_PORT

This script will run database migrations (rake db:migrate) which should be idempotent.

It will also seed the database (rake db:seed) unless this is defined:

DO_NOT_SEED

This same seeding initially defines the "admin" user with a default password of "password" as per the standard Huginn documentation.

If you do not wish to have the default 6 agents, you will want to set the above environment variable after your initially deploy, otherwise they will be added automatically the next time a container pointing at the database is spun up.

The CMD launches Huginn via the scripts/init script. This may become the ENTRYPOINT later. It does take under a minute for Huginn to come up. Use environmental variables that match your DB's creds to ensure it works.

Usage

Simple stand-alone usage:

docker run -it -p 5000:5000 cantino/huginn

To link to another mysql container, for example:

docker run --rm --name newcentury_mysql -p 3306 \
    -e HUGINN_MYSQL_DATABASE=huginn \
    -e HUGINN_MYSQL_USER=huginn \
    -e HUGINN_MYSQL_PASSWORD=somethingsecret \
    -e HUGINN_MYSQL_ROOT_PASSWORD=somethingevenmoresecret \
    cantino/huginn
docker run --rm --name huginn --link newcentury_mysql:MYSQL -p 5000:5000 \
    -e HUGINN_DATABASE_NAME=huginn \
    -e HUGINN_DATABASE_USER=huginn \
    -e HUGINN_DATABASE_PASSWORD=somethingsecret \
    cantino/huginn

To link to another container named 'postgres':

docker run --rm --name huginn --link POSTGRES:mysql -p 5000:5000 -e "DATABASE_USER=huginn" -e "DATABASE_PASSWORD=pass@word" cantino/huginn

These are:

The above environment variables will override the defaults. The defaults are read from the .env.example file.

For variables in the .env.example that are commented out, the default is to not include that variable in the generated .env file.

Building on your own

You don't need to do this on your own, because there is an automated build for this repository, but if you really want:

docker build --rm=true --tag={yourname}/huginn .
