Docker-compose

[Priyanka-Cloud-Infinite]

Hello Sir,
I am following your course to sharp my Ansible skill. I am facing a problem with the installation pahase.
When I type docker-compose it will generate

When I type localhost:1000 I get this

Cloud you guide my next steps to resolve the issue?

Hi @Priyanka-Cloud-Infinite

Thanks for reaching out to me on this and for the shared screenshots.

It looks like you're using Ubuntu under WSL2 and the issue you're encountering, relates to this version of Ubuntu being stripped down for use on Windows. In your output you can see that the Ubuntu containers are exiting with 255 errors.

There's an easy fix, if you have a look on the main repo page on GitHub and search for 255, you'll find details of how to resolve this.

Have a look and let me know how you get on 👍

Best Regards

HI @spurin

I'm having the same error in native installation of ubuntu 20.04. Any idea?

Thanks

Hi @steevi

Could you please tell me more about the setup? i.e. when you say Native, is this on bare metal, running in a VM, in cloud or something else. As much information as possible.

Could you also please share with me your .env file and output of the failure.

Will take a look.

Thanks

Thanks for the quick reply @spurin .
Ubuntu 20.04.2 is installed locally on a laptop. Hardware wise think i don't have an issue (8 cores/16 threads, 16GB RAM).

my .env file is the following:

# Shared config volume
CONFIG=/home/steevi/diveintoansible-lab/config

# Shared home directories
ANSIBLE_HOME=/home/steevi/diveintoansible-lab/ansible_home

Doing docker inspect on the ubuntu images, couldn't see any entrypoint or command. I'm familiar a lot with docker but not with ansible :/

Can help to debug if you want

[spurin]

The specs should be absolutely fine and your config looks okay. Can you share the output of it failing please.

Thanks

[steevi]

@spurin Is that ok?

[spurin]

Thanks @steevi

That's great. You really shouldn't have any issues. We'll dig into this a bit further, could you provide me with -

1. Output of systemctl

2. Output of mount command

3. More info on the setup/install process. If you have the reference to the image you used that will help. Also, did you happen to do anything in particular, like a minimal install?

[steevi]

1. Is the following what you need?

Hi @steevi

Apologies, I have got sidetracked on this. Please let me know if you'd like to continue troubleshooting this further.
