!! Developing
Our source code has been copied from the github repo to an internal RedHat repo. The overview page tells use what this RedHat git repo is: __ssh://583f185e2d5271b8c6000069@diy-computerhok.rhcloud.com/~/git/diy.git/__ . %%warning I don't see an option for an https URL %%
So we (locally) add this remote repo : {{git remote add openshift ssh://583f185e2d5271b8c6000069@diy-computerhok.rhcloud.com/~/git/diy.git/}}.
We also have to provide special [Action hooks|https://developers.openshift.com/managing-your-applications/action-hooks.html] because we have to specify how to start our application, and we have to specify the port to listen on (the latter can be solved better/differently I think).
So created 3 additional scripts in our git repo:
* .openshift/action_hooks/build
* .openshift/action_hooks/deploy
* .openshift/action_hooks/start
Containing:
__build__
%%prettify
{{{
#!/bin/bash
gradle assemble
}}}
At line 255 removed 129 lines
__deploy__
%%prettify
{{{
#!/bin/bash
echo "current dir 1: `pwd`"
cd $OPENSHIFT_REPO_DIR
echo "current dir 2: `pwd`"
ls -la
sed -i 's/@OPENSHIFT_DIY_IP@/'"$OPENSHIFT_DIY_IP"'/g' src/main/resources/demoapp1.openshift.yaml
sed -i 's/@OPENSHIFT_DIY_PORT@/'"$OPENSHIFT_DIY_PORT"'/g' src/main/resources/demoapp1.openshift.yaml

}}}
%%
Then when we git push (1), this was before we had the bulid script :
{{{

}}}
It tells us all success, but the app still fails (503 response). How to diagnose further, the UI does not show anything about status or logs. Let's try the ssh again.
Then we added the build hook script and pushed again:
{{{

The idea is to just a container from an image, and that envvars should determine which jar file to run.
