title: Podman
|
|
---
|
|
|
|
## I am seeing host not found error in the logs. How do I fix it?
|
|
|
|
This should be mainly a Podman only error: Using Podman doesn't create an engine-id like Docker.
|
|
If you are using Docker, check if the `engine-id` file exists with correct permissions in `/var/lib/docker` and has the UUID inside.
|
|
|
|
It might be necessary to clean up your existing Dozzle deployment under Podman, stop the container and remove the associated data (container/volumes). After you create the engine-id, you can redeploy the Dozzle container and your logs should now show up.
|
|
|
|
## Create UUID
|
|
|
|
Options for generating UUIDs:
|
|
|
|
### uuidgen
|
|
|
|
:warning: Adjust folder/file permissions if necessary. There isn't any critical info but depending on your existing setup you might want to take additional steps.
|
|
|
|
1. Install uuidgen
|
|
2. Create the folders: `mkdir -p /var/lib/docker`
|
|
3. Using uuidgen generate a UUID: `uuidgen > /var/lib/docker/engine-id`
|
|
4. Verify with `cat /var/lib/docker/engine-id`
|
|
|
|
### Ansible
|
|
|
|
:warning: Depending on your setup you might have to make adjustments for file/folder permissions. The following task snippets would run as the become_user/remote_user of the playbook running these tasks.
|
|
|
|
If you wish to adjust the user, you have to set individual become/become_user parameters for these tasks.
|
|
|
|
```yaml
|
|
- name: Create /var/lib/docker
|
|
ansible.builtin.file:
|
|
path: /var/lib/docker
|
|
state: directory
|
|
mode: "755"
|
|
|
|
- name: Create engine-id and derive UUID from hostname
|
|
ansible.builtin.lineinfile:
|
|
path: /var/lib/docker/engine-id
|
|
line: "{{ hostname | to_uuid }}"
|
|
create: true
|
|
mode: "0644"
|
|
insertafter: "EOF"
|
|
```
