I don’t know much about docker compose but I have set up AWX 17.0.0 in Kubernetes cluster without any issues. Can you check if postgresql container is up and running since I see something about that in the error? Thanks ---

Hi, Have you installed Docker & Docker Compose accordingly? I followed this instructions below and worked for me, it is for Ubuntu, but it does not matter, just replace some specific “flavored” commands: [https://computingforgeeks.com/how-to-install-ansible-awx-on-ubuntu-linux/](https://computingforgeeks.com/how-to-install-ansible-awx-on-ubuntu-linux/) ---

Did you run the steps in the readme: [https://github.com/ansible/awx/blob/devel/INSTALL.md#kubernetes](https://github.com/ansible/awx/blob/devel/INSTALL.md#kubernetes) Just want to make sure I am not missing anything while running down this rabbit hole. 🙂 Thanks! ---

Can you share how your inventory looks like? ---

Did you install the docker and docker-compose rpms? can you do a docker pull of the awx and postgresql images from dockerhub or where ever your docker image repository is pointing to from the machine you are installing this on? Michael
