Troubleshooting¶
Image Pull Backoff¶
This could have the following reasons:
- You are notified that your images repositories credentials are incorrect or the image doen`t exists.
- Your image is very big.
- You use persistent storage for your code. Which slows down the inital startup.
Image tag latest gives 500¶
- Try to find an older version of that image that works.
Your pod returns a 500 errors / Using an image with code errors¶
Things to consider:
- latest image is broken
- try a different image
- your code might be broken, try to fix the code
- the data in the database might be awkward and might cause the application to fail
- binary data might be missing that causes an exception in the code
Your POD IP is not reachable¶
- You might be running two developer CRCs that use the same external IP
The result you see in the browser is not the result you expect¶
- You have been using your OS hosts file to address the POD, meanwhile you changed the IP of the POD and your hosts file, but browser doesn`t notice. Restart the browser.
Can`t login via ssh¶
Error: child_set_env: too many env vars

This can be fixed by removing the amount of pods in a namespace.
Dev the system is slow in general¶
Here are hint on how fast a System should be
| Scenario | Result |
|---|---|
| APP_ENV=prod, XDEBUG_MODE=, BLACKFIRE-*= | Request will take 1 sec it has no overhead |
| APP_ENV=dev,APP_DEV=1, XDEBUG_MODE=, BLACKFIRE-*= | Request will take 3 sec it has overhead of the webdeveloper toolbar |
| APP_ENV=dev,APP_DEV=1, XDEBUG_MODE=develop, BLACKFIRE-*= | Request will take 6, if the IDE is connected. It will take 60+ sec if the IDE is not listending to the request, because XDEBUG can`t reach the IDE (timeout). See /tmp/xdebug.log |
| APP_ENV=prod,APP_DEV=,XDEBUG_MODE=, BLACKFIRE-*=XXX | Request will take 4 sec, has overhead of the Blackfire runnign in the background |
If you use the env APP_DEV set to dev the system is slow¶
- Check the logs. There might be to many unseen errors.
If you use the env XDEBUG_MODE set to dev the system is slow¶
- Check /tmp/xdebug.log for connection errors, this mean you have not startet the remote debugging
- If you do not need to debug pph code remove XDEBUG_MODE from env
You see an out of memory error¶
- You might have var_dump in the code.
