If I clone rel-502 and run with the docker-compose.yml, the container never finishes installation, failing with the text at the bottom of this post. When I use the docker-compose.yml in the current devops version, it fails a few times while mysql is loading then completes. Is there some difference between the docker image of 5.0.2 used by devops ([openemr-devops/docker/openemr/5.0.2 at master · openemr/openemr-devops · GitHub](https://github.com/openemr/openemr-devops/tree/master/docker/openemr/5.0.2)) and the resulting image made directly from 5.0.2? Is there something incorrect in the docker-compose.yml file coming with 5.0.2?

Couldn’t set up. Any of these reasons could be what’s wrong:

- You didn’t spin up a MySQL container or connect your OpenEMR container to a mysql instance
- MySQL is still starting up and wasn’t ready for connection yet
- The Mysql credentials were incorrect

Hi Derek,

Can you paste the docker-compose.yml script that you are using.  
It sounds like you are using a flex docker (can confirm that when see the docker-compose.yml); if so, ensure you are using most recent image:  
[OpenEMR flex docker updated](https://community.open-emr.org/t/openemr-flex-docker-updated/12051/11)

I just needed to  
docker pull openemr/openemr:flex  
as you suggested. I didn’t practice good image hygiene and most of my local images were way old.

Thank you so much Brady, your leadership and support is very appreciated.

Thanks,  
Derek
