Setup

Set up mysql containers and Dreamwidth container

docker run -d --name mysql-data -v /var/lib/mysql -v /var/log/mysql busybox /bin/true
docker build -t dreamwidth/mysql mysql

docker build -t dreamwidth/web dreamwidth
docker build -t dreamwidth/nginx-dev nginx-dev

Start mysql

Change the password! Note: it's only used here once; everywhere else refers to it using passwords

docker run --name mysql-db --volumes-from mysql-data -e MYSQL_ROOT_PASSWORD=mysecretpassword -d dreamwidth/mysql

(FIRST RUN) Setup repo

Fork repository on Github
Clone repository onto your computer
Set your LJHOME variable to where your repository was cloned

(FIRST RUN) Setup database

docker run --entrypoint "/bin/bash" -it -v $LJHOME:/dw --link mysql-db:db --rm dreamwidth/web
> /opt/init-db.sh

Start Dreamwidth web server

This is not exposed until we run the nginx server below.

# -d : detach and run in background
# --name dw-web : create an easy-to-remember consistent way to refer to this container
# -v $LJHOME:/dw : take your repository code (in $LJHOME) and run it inside the container.
                   Any changes you make to files will be reflected immediately.
                   Note: this overrides your config-private.pl to use the docker-specific DB settings
                   See Configuration section below
# --link mysql-db:db : use the mysql database container you created above
# dreamwidth/web : the container name we should use

docker run -d --name dw-web -v $LJHOME:/dw -it --link mysql-db:db dreamwidth/web

Start Dreamwidth nginx server

This runs in front of the Apache server and handles serving up static files and HTTPS.

# -p 80:80 / 443:443 : exposes ports 80 and 443 to the host

docker run -d --name dw-nginx -v $LJHOME:/dw:ro -it --link dw-web:web -p 80:80 -p 443:443 dreamwidth/nginx-dev

Optional containers:

proxy

docker build -t dreamwidth/proxy proxy
docker run -d --name dw-proxy -v $LJHOME/ext/local/etc/proxy-salt:/proxy-salt -it dreamwidth/proxy

If you're making changes to the proxy code, you'll want to override the code in /dw as well:

docker run -d --name dw-proxy -v $LJHOME:/dw -v $LJHOME/ext/local/etc/proxy-salt:/proxy-salt --entrypoint "/opt/custom-build.sh" -it dreamwidth/proxy

Running dw-nginx also needs an additional --link dw-proxy:proxy:

docker run -d --name dw-nginx -v $LJHOME:/dw:ro -it --link dw-proxy:proxy --link dw-web:web -p 80:80 -p 443:443 dreamwidth/nginx-dev

Wiki has additional information for proxy setup.

Normal operations

Run

docker start mysql-db dw-web dw-nginx

Stop

docker stop mysql-db dw-web

Connecting to your webserver

curl 127.0.0.1             # not mac
curl `boot2docker ip`      # mac

Testing

Connect to mysql from a test container

docker run --entrypoint "/bin/bash" -v $LJHOME:/dw -it --link mysql-db:db --rm dreamwidth/web
mysql -uroot -h $DB_PORT_3306_TCP_ADDR -P $DB_PORT_3306_TCP_PORT -p$DB_ENV_MYSQL_ROOT_PASSWORD

Attach to dreamwidth web and look around

Commandline prompt doesn't show for the first line, but it's active

docker attach dw-web

Detach

Ctrl+p, Ctrl+q

Look at the webserver logs

docker exec dw-web tail /var/log/apache2/error.log

Configuration

The containers will handle connecting between the various containers.

Settings you SHOULD NOT define:

@LJ::DBINFO, @LJ::THESCHWARTZ_DBS, $LJ::DOMAIN

You'll also want to add hack.dw, to your /etc/hosts file. Example:

# standard entries
127.0.0.1 hack.dw www.hack.dw system.hack.dw

# services
127.0.0.1 proxy.hack.dw

# your test user accounts
127.0.0.1 testuser.hack.dw some-community.hack.dw

If you're on a Mac, use the result of boot2docker ip instead of 127.0.0.1.
