Hi!

this is my .env file:

# sshd ports
UBUNTUC_PORT_SSHD=2221
UBUNTU1_PORT_SSHD=2222
UBUNTU2_PORT_SSHD=2223
UBUNTU3_PORT_SSHD=2224

CENTOS2_PORT_SSHD=2226
CENTOS3_PORT_SSHD=2227

# ttyd (web terminal) ports
UBUNTUC_PORT_TTYD=7681
UBUNTU1_PORT_TTYD=7682
UBUNTU2_PORT_TTYD=7683
UBUNTU3_PORT_TTYD=7684

CENTOS3_PORT_TTYD=7687

# Shared config volume
CONFIG=/home/{{user}}/diveintoansible-lab

# Shared home directories
ANSIBLE_HOME=/home/{{user}}/.ansible`

This is the output of docker-compose up command:

`docker-compose up

Given that the autocreate dirs feature for bind volumes is deprecated, I created dirs manually just in case, with these commands:
docker/compose#2781

`mkdir -p ~/.ansible/ubuntu[1,2,3]
mkdir -p ~/.ansible/centos[1,2,3]
mkdir -p ~/.ansible/ubuntu-c
mkdir -p ~/.ansible/shared

Still I couldn't make it work. Any suggestions?, centos images run but ubuntu ones don't. I also checked the layers but I really couldn't find what is happening.

Thanks in advance, and hope this helps others.

Hi Spurin!,

Thanks for your quick reply. Ok, for some reason I copied over the .env file without the config part. Now I didn't create any dirs manually, you are totally right it creates the dirs automatically, but not sure why docker-compose creates the dirs as root.

.env

# sshd ports

UBUNTU1_PORT_SSHD=2222

UBUNTU1_PORT_TTYD=7682

Hi Oscar,

I think you can ignore the permissions on the directory, Docker is running as root and docker-compose is passing off to Docker, hence the permissions. We'll get to the bottom of this, even if we need to break it down into stages.

Just seeing how we can break this up for further testing, will update shortly.

Thank you very much. I could make this work perfect in a vagrant box, so I am concerned it maybe has to do with something in docker vs using WSL2 engine.

spurin commented Dec 18, 2020

It's a good opportunity to find out whats wrong so we'll try and troubleshoot this for now. Okay, some stages -

Let's see if you can run the ansible container as it is, quite simply, you should get a login and then just be able to exit -

docker run --rm -p 12345:7681 --privileged -it spurin/diveintoansible:ansible bash

@oscarmparedes

This works.

docker run --rm -p 12345:7681 --privileged -it spurin/diveintoansible:ansible bash
root@49c0e35574e7:/# exit
exit

Next, let's test the directory mounts -

docker run -v /home/oscar/diveintoansible-lab/config:/config -v /home/oscar/diveintoansible-lab/ansible_home --rm -p 12345:7681 --privileged -it spurin/diveintoansible:ansible ls /config /ansible_home

Okay so thats interesting. By the way, are you running this as a standalone Linux Ubuntu system or is it running in another virtualisation layer?

Let's see the permissions -

ls -ald /home/oscar/diveintoansible-lab/ansible_home

Ok this is docker desktop for windows with WSL2 engine enabled. I am using a WLS2 ubuntu 20.04 image.

 ls -ald /home/oscar/diveintoansible-lab/ansible_home
drwxr-xr-x 10 root root 4096 Dec 18 19:43 /home/oscar/diveintoansible-lab/ansible_home

It was docker-compose that created this dir btw. It does work perfectly fine in an Ubuntu 20.04 Vagrant box.

Understood. You could also directly run the lab from Windows and I don't think you'll have these problems.

Let's try this -

id
mkdir -p /home/oscar/diveintoansible-lab/ansible_home2
docker run -v /home/oscar/diveintoansible-lab/config:/config -v /home/oscar/diveintoansible-lab/ansible_home2 --rm -p 12345:7681 --privileged -it spurin/diveintoansible:ansible ls /config /ansible_home

Sure, I am actually testing this for a friend that started your course. I am using my work laptop (windows only), and I need WSL2 to have linux for work. I think the WSL2 is doing something strange with permissions.

id
uid=1000(oscar) gid=1000(oscar) groups=1000(oscar),4(adm),20(dialout),24(cdrom),25(floppy),27(sudo),29(audio),30(dip),44(video),46(plugdev),117(netdev),1001(docker)

Okay great, earlier on it was missing the :/ansible_lab bit, can you try this for me next please -

docker run --name diveintodebug -v /home/oscar/diveintoansible-lab/config:/config -v /home/oscar/diveintoansible-lab/ansible_home/ubuntu-c/ansible:/home/ansible -v /sys/fs/cgroup:/sys/fs/cgroup:ro --rm -p 12345:7681 --privileged -it spurin/diveintoansible:ansible

You should, if all goes well be able to login to http://localhost:12345

Can you try this out and share the output, if it's not working. Note, to stop this, you'll need a new terminal and will need to do -

docker stop diveintodebug

This is great and I hope it is useful for someone else I think I found a fix. So for the record:

Looks like it works by using this. So if anyone is using Docker for windows with WSL2 engine, maybe this is the fix for your lab to work in this kind of environment. microsoft/WSL#4189

More precisely, if using WSL2, and Docker for windows with WSL2 engine support enabled, try running like this:

sudo mkdir -p /sys/fs/cgroup/systemd
:~/diveintoansible-lab$ sudo mount -t cgroup -o none,name=systemd cgroup /sys/fs/cgroup/systemd
:~/diveintoansible-lab$ docker-compose up

Creating portal   ... done
Attaching to ubuntu2, ubuntu1, ubuntu-c, centos2, centos1, ubuntu3, docker, centos3, portal

As per answering your questions, the tests we were doing before were done from WSL2 Ubuntu 20.04 box, not Vagrant. Vagrant worked fine from the beginning is just this setup. It's just a workaround, not a proper fix, I will keep investigating.

Very cool lab by the way. Congrats!
