Bug With running docker compose up

[Honigeintopf]

Running the docker compose up gives me:

ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ docker compose up [+] Running 9/0 ✔ Container docker Created 0.0s ✔ Container ubuntu2 Created 0.0s ✔ Container centos2 Created 0.0s ✔ Container centos3 Created 0.0s ✔ Container ubuntu1 Created 0.0s ✔ Container centos1 Created 0.0s ✔ Container ubuntu3 Created 0.0s ✔ Container ubuntu-c Created 0.0s ✔ Container portal Created 0.0s Attaching to centos1, centos2, centos3, docker, portal, ubuntu-c, ubuntu1, ubuntu2, ubuntu3 centos2 exited with code 255 ubuntu-c exited with code 255 ubuntu1 exited with code 255 centos1 exited with code 255 centos3 exited with code 255 ubuntu3 exited with code 255 ubuntu2 exited with code 255 portal | 2024/09/19 10:33:30 [emerg] 1#1: host not found in upstream "centos1" in /etc/nginx/conf.d/default.conf:15 portal | nginx: [emerg] host not found in upstream "centos1" in /etc/nginx/conf.d/default.conf:15 portal exited with code 1

I hope you didn't download anything from @Felipe-Rafael-Rosa - this was a malware attempt, have deleted the comment.

@Honigeintopf - Have you ever installed/run the lab environment before?

What operating system are you using and which version (if Windows, please share details of start/run/winver)

[Honigeintopf]

First time installing the environment. Im using Ubuntu 24.04, newest version of docker compose. Cloned it into my home directory.

ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ docker compose version
Docker Compose version v2.29.2
ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ pwd
/home/ebubekir/diveintoansible-lab
ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ ls
ansible_home  config  DiveIntoAnsible_Cover.png  docker  docker-compose.yaml  README.md
ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$

Thanks @Honigeintopf, this is unusual. How did you setup Docker?

Also, I'm assuming your system is x64, is that correct.

[spurin]

We can try running the containers manually and seeing if there is an error, if you try any of the following and press return a few times, hopefully it will put you into a bash shell in the container, type exit to exit the shell and cleanup -

docker run -it --rm --privileged spurin/diveintoansible:centos /bin/bash

docker run -it --rm --privileged spurin/diveintoansible:ubuntu /bin/bash

[spurin]

In the interim, the Google Cloud Shell option can be used but let's work on seeing if we can resolve this. We'll try this out and failing this, I'll setup a 24.04 environment.

[Honigeintopf]

I can exec into them and ls. I have setup docker just basic, downloaded it from the official repo with apt.

[spurin]

Okay so you can run these containers by the look of it, without them failing, the main difference will be the container mounts.

Can you run an ls -ald on ansible-home and also do a find ansible-home

[Honigeintopf]

ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ ls
ansible_home  config  DiveIntoAnsible_Cover.png  docker-compose.yaml  README.md
ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$  ls -ald

find: ‘ansible-home’: No such file or directory
ebubekir@ebubekir-XPS-15-9500:~/diveintoansible-lab$ 

find is failing?

[spurin]

My bad this should be ansible_home

Thank you, this helps, when you say that you installed via apt, could you elaborate as this could mean a few different things and I want to make sure I'm replicating your experience.

[spurin]

Also, could you please run and share the output from the following -

docker run --rm alpine cat /proc/self/uid_map

[Honigeintopf]

I reinstalled it again, with this. Now it is working, so it was a broken docker installation.

https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository

[spurin]

And

docker --version

Thanks

[Honigeintopf]

Thank you for the help! I will close this issue.

[spurin]

Hey @Honigeintopf - Thank you, just for my benefit, how did you install prior to this?

[Honigeintopf]

Not really sure it's been a while, but it worked with every thing else I'm working on. I probably used the .deb package.

https://docs.docker.com/desktop/install/linux/ubuntu/

[spurin]

Super, thanks for confirming @Honigeintopf - I typically use the curl https://get.docker.com | sudo bash approach, it's quick, convenient and works well.
