-## Troubleshooting

-### Errors due to permissions
-
-If you see errors about permissions, then you may need to review the options for the securityContext.

-### Errors due to authentication
-
-If you're having issues getting your registry authentication to work, then why not try out ttl.sh, a free, ephemeral container registry. [ttl.sh](https://ttl.sh) is a public service run by Replicated, which allows you to push and pull images without authentication.

-Once you've seen the building work end to end, get in touch with us and we'll try to help you with your authentication.
