security : generate new grub config fails

[pheidrias]

Hello and thanks for this great playbook!

I'm running into the following trouble:

RUNNING HANDLER [security : generate new grub config] *************************************
fatal: [mydomain.de]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'grub_cfg' is undefined\n\nThe error appears to be in '/home/myuser/ansible/ansible-workadventure/roles/security/handlers/main.yml': line 59, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: \"generate new grub config\"\n  ^ here\n"}

I couldn't find, where grub_cfg should be configured or what the grub cmd-line is supposed to look like :-(... It seems, that the following docker-compose has issues with cgroup - is this related?

What other information can I provide to help?

Reproduction steps:

• clean debian minimal install via image from netcup.de
• ssh-copy pub key
• create vault, edit deployment.yml
• run ansible

Thanks in advance, pheidrias

Update: I updated grub manually with the information from roles/docker_setup/tasks/setup_docker.yml, to look like: GRUB_CMDLINE_LINUX="net.ifnames=0 transparent_hugepage=never video=1024x768 audit=1 cgroup_enable=memory systemd.unified_cgroup_hierarchy=0 audit=1"

But docker-compose still has problems (probably unrelatedI:

/opt/workadventure# docker-compose up -d

I do get a 404 when trying to access "my" workadventure :-(...(subdomains point to my server's IP)

regarding grub: The file is in /etc/default/grub and the Line should be the following:

GRUB_CMDLINE_LINUX="quiet cgroup_enable=memory systemd.unified_cgroup_hierarchy=0"

regarding docker: maybe you want to execute docker logs -f workadventure_front_1. It should tell you more about the issue.

What I find irritating, is WARNING: The START_ROOM_URL variable is not set. Defaulting to a blank string. Have a look in the .env-File. It lies right next to your docker-compose.yml. My template is in env.j2. The variables are filled in the deployment.yml .

Hello again,

I found the problem with my personal installation - due to too many new applications for letsencrypt I didn't get a new certificate. I did find out with the help of your dockker logs suggestion - thanks!

Nevertheless, the grub-problem with your ansible script remains. Where should "grub_cfg" come from (as it is not set)?
