## Setup certbot Project
|
||||
|
||||
- [ ] Copy and rename this folder to active/podman_certbot
|
||||
- [ ] Find and replace certbot with the name of the service.
|
||||
- [ ] Create the rootless user to run the podman containers
|
||||
- [ ] Write the compose.yaml spec for your service
|
||||
- [ ] Convert the compose.yaml spec to a quadlet
|
||||
- [ ] Install the quadlet on the podman server
|
||||
- [ ] Expose the quadlet service
|
||||
- [ ] Install a backup service and timer
|
||||
|
||||
## Install certbot
|
||||
|
||||
### Create the certbot user
|
||||
|
||||
```bash
|
||||
# SSH into your podman server as root
|
||||
useradd certbot
|
||||
loginctl enable-linger $(id -u certbot)
|
||||
systemctl --user --machine=certbot@.host enable podman-restart
|
||||
systemctl --user --machine=certbot@.host enable --now podman.socket
|
||||
mkdir -p /home/certbot/.config/containers/systemd
|
||||
```
|
||||
|
||||
### Write the certbot compose spec
|
||||
|
||||
```bash
|
||||
podman run -it --rm --name certbot \
|
||||
-v "/etc/letsencrypt:/etc/letsencrypt:Z" \
|
||||
-v "/var/lib/letsencrypt:/var/lib/letsencrypt:Z" \
|
||||
certbot/certbot certonly -d keycloak.reeseapps.com -d keycloak.reeselink.com
|
||||
|
||||
```
|
||||
|
||||
#### A Note on Volumes
|
||||
|
||||
Named volumes are stored at `/home/certbot/.local/share/containers/storage/volumes/`.
|
||||
|
||||
### Convert certbot compose spec to quadlets
|
||||
|
||||
Run the following to convert a compose.yaml into the various `.container` files for systemd:
|
||||
|
||||
```bash
|
||||
# Generate the systemd service
|
||||
podman run \
|
||||
--security-opt label=disable \
|
||||
--rm \
|
||||
-v $(pwd)/active/podman_certbot/:/compose \
|
||||
-v $(pwd)/active/podman_certbot/quadlets:/quadlets \
|
||||
quay.io/k9withabone/podlet \
|
||||
-f /quadlets \
|
||||
-i \
|
||||
--overwrite \
|
||||
compose /compose/compose.yaml
|
||||
|
||||
# Copy the files to the server
|
||||
export PODMAN_SERVER=
|
||||
scp -r active/podman_certbot/quadlets/. $PODMAN_SERVER:/home/certbot/.config/containers/systemd/
|
||||
ssh $PODMAN_SERVER chown -R certbot:certbot /home/certbot/.config/containers/systemd/
|
||||
```
|
||||
|
||||
### Create any container-mounted directories
|
||||
|
||||
SSH into your podman server as root:
|
||||
|
||||
```bash
|
||||
machinectl shell certbot@
|
||||
podman unshare
|
||||
mkdir some_volume
|
||||
# Chown to the namespaced user with UID 1000
|
||||
# This will be some really obscure UID outside the namespace
|
||||
# This will also solve most permission denied errors
|
||||
chown -R 1000:1000 some_volume
|
||||
```
|
||||
|
||||
### Start and enable your systemd quadlet
|
||||
|
||||
SSH into your podman server as root:
|
||||
|
||||
```bash
|
||||
machinectl shell certbot@
|
||||
systemctl --user daemon-reload
|
||||
systemctl --user restart certbot
|
||||
# Enable auto-update service which will pull new container images automatically every day
|
||||
systemctl --user enable --now podman-auto-update.timer
|
||||
```
|
||||
|
||||
### Expose certbot
|
||||
|
||||
1. If you need a domain, follow the [DDNS instructions](/active/podman_ddns/ddns.md#install-a-new-ddns-service)
|
||||
2. For a web service, follow the [Caddy instructions](/active/podman_caddy/caddy.md#adding-a-new-caddy-record)
|
||||
3. Finally, follow your OS's guide for opening ports via its firewall service.
|
||||
|
||||
#### firewalld
|
||||
|
||||
```bash
|
||||
# command to get current active zone and default zone
|
||||
firewall-cmd --get-active-zones
|
||||
firewall-cmd --get-default-zone
|
||||
|
||||
# command to open 443 on tcp
|
||||
firewall-cmd --permanent --zone=<zone> --add-port=443/tcp
|
||||
|
||||
# command to open 80 and 443 on tcp and udp
|
||||
firewall-cmd --permanent --zone=<zone> --add-port={80,443}/{tcp,udp}
|
||||
|
||||
# command to list available services and then open http and https
|
||||
firewall-cmd --get-services
|
||||
firewall-cmd --permanent --zone=<zone> --add-service={http,https}
|
||||
```
|
||||
|
||||
## Backup certbot
|
||||
|
||||
Follow the [Borg Backup instructions](/active/systemd_borg/borg.md#set-up-a-client-for-backup)
|
||||
|
||||
## Upgrade certbot
|
||||
|
||||
### Upgrade Quadlets
|
||||
|
||||
Upgrades should be a repeat of [writing the compose spec](#convert-certbot-compose-spec-to-quadlets) and [installing the quadlets](#start-and-enable-your-systemd-quadlet)
|
||||
|
||||
```bash
|
||||
export PODMAN_SERVER=
|
||||
scp -r quadlets/. $PODMAN_SERVER$:/home/certbot/.config/containers/systemd/
|
||||
ssh certbot systemctl --user daemon-reload
|
||||
ssh certbot systemctl --user restart certbot
|
||||
```
|
||||
|
||||
## Uninstall
|
||||
|
||||
```bash
|
||||
# Stop the user's services
|
||||
systemctl --user disable podman-restart
|
||||
podman container stop --all
|
||||
systemctl --user disable --now podman.socket
|
||||
systemctl --user disable --now podman-auto-update.timer
|
||||
|
||||
# Delete the user (this won't delete their home directory)
|
||||
# userdel might spit out an error like:
|
||||
# userdel: user certbot is currently used by process 591255
|
||||
# kill those processes and try again
|
||||
userdel certbot
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
### SELinux
|
||||
|
||||
<https://blog.christophersmart.com/2021/01/31/podman-volumes-and-selinux/>
|
||||
|
||||
:z allows a container to share a mounted volume with all other containers.
|
||||
|
||||
:Z allows a container to reserve a mounted volume and prevents any other container from accessing.
