SwitchingBranches
There might be the time when a Docker image with the latest code changes is not available or you need to check out a different branch of an OBP service. This page will explain how you can accomplish that.
You need the container id, e.g. by checking ps
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5daeadd895cd dde5c1d02fee "/bin/sh -c /usr/loca" About an hour ago Up About an hou 0.0.0.0:8080-8082->8080-8082/tcp fervent_heisenberg
In this case, it will be 5daeadd895cd.
Then enter the container like this:
$ docker exec -it 5daeadd895cd /bin/bash
The options to exec mean: interactive and allocate pseudo-tty, so input and output will work properly. The result should look like:
root@5daeadd895cd:/#
Now change to the directory of the OBP service you want to switch the branch to:
root@5daeadd895cd:/# cd /opt/OBP/Social-Finance
Next you switch the branch and pull the latest code
root@5daeadd895cd:/opt/OBP/Social-Finance# git checkout 2015-11-design && git pull
Although things might already work now, it's probably safer to clean the code base and (re)compile afterwards:
root@5daeadd895cd:/opt/OBP/Social-Finance# ./mvn.sh clean && ./mvn.sh compile
This might take a while, depending on your machine.
Usually jetty realises the code change and restarts automatically. If it doesn't, you can tell supervisor manually to restart the service.
root@5daeadd895cd:/opt/OBP/Social-Finance# supervisorctl restart Social-Finance
Finally point your browser at the service, e.g. http://localhost:8081/ .
If things don't work, the supervisor log files in /var/log/supervisor might help, e.g.
root@5daeadd895cd:/# tail -f /var/log/supervisor/Social-Finance-stdout.log
Note that less or sophisticated text editors are not installed in the container. You can install them by running:
root@5daeadd895cd:/# apt-get install less vim
