Setting up docker containers for the OUTSTEP web application

Setting up mysql docker container with persistent storage

First change to the mysql directory:

cd mysql/

To allow for the databases to persist in the image, we use the following Dockerfile:

FROM mysql:latest
RUN cp -r /var/lib/mysql /var/lib/mysql-no-volume
CMD ["--datadir", "/var/lib/mysql-no-volume"]

Next, build and run,

docker build . -t o-mysql
docker run -p 3306:3306 \
       --name <db-container-name> \
       -e MYSQL_ROOT_PASSWORD=<root_password> \
       -e MYSQL_USER=<username> \
       -e MYSQL_PASSWORD=<password> \
       -ti o-mysql

Note that in some systems you might have to use sudo docker instead of docker.

You can given any tag to the image instead of o-mysql.

Setting up database

Use the create and populate scripts.

docker exec -it <db-container-name> mysql -uroot -p -e "$(cat createdb.sql)"

Populating data

docker exec -it <db-container-name> mysql -u<username> -p -e "$(cat popualtedb.sql)"

Running the node.js server

From the repository root, change to the nodejs directory:

cd nodejs/

Build and run the docker image,

docker build -t o-nodejs .
docker run -p 8080:8080 -d o-nodejs

Again, you can give any name to the image that is built here.

Building the rocket.chat app

From the repository root, change to the rocketchat directory:

cd rocketchat/

We will be using the docket-compose.yml file (you can modify some of the option, if needed). In particular, you need to replace the ROOT_URL field with the appropriate URL.

Also, we are going to use the /data and /uploads directory on the host to store the data. Make sure that those directories exist and have the correct permissions.

docker-compose up -d mongo
docker-compose up -d mongo-init-replica
docker-compose up -d rocketchat

After setting up the application by visiting the URL on a browser, you can create a bot to talk to. Edit the file docker-compose.yml again to change the variables ROCKETCHAT_USER and ROCKETCHAT_PASSWORD in the hubot section and then start up hubot:

docker-compose up -d hubot
