+## Container
+https://docs.gitlab.com/ee/install/docker.html  
+```
+# podman run -d --name gitlab \
+    --hostname gitlab.exu.li \
+    -p 8080:80 -p 2222:22 \
+    --volume /mnt/gitlab/config:/etc/gitlab \
+    --volume /mnt/gitlab/logs:/var/log/gitlab \
+    --volume /mnt/gitlab/data:/var/opt/gitlab \
+    --shm-size 256m \
+    docker.io/gitlab/gitlab-ce:latest
+```
+
+Starting the container for the first time takes a while  
+
+After it is done, this command can be used to access the password for the initial `root` account.  
+`# podman exec -it gitlab grep 'Password:' /etc/gitlab/initial_root_password`  
+Make sure to do this within 24h after starting the container. The file will be deleted after that.  
+
+## Configuration
+The main configuration file is `/etc/gitlab/gitlab.rb` in the container.  
+GitLab can reread its configuration file by using the command `gitlab-ctl reconfigure` in the container.  
+
+### Correct external URL
+```
+external_url 'https://(url)'
+```
+
+### SMTP for email
+```
+...

+# can change the 'From' with this setting.
