The python:3.11-slim job container lacked a Node.js runtime, so the runner couldn't exec actions/checkout inside it. Run jobs on the default runner image instead and pin Python via actions/setup-python. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# Deploying on a KIT HPC login node (no Docker daemon)
|
|
|
|
This path is for machines like the ETP login nodes: `/ceph`, `/work`, `/web` are
|
|
mounted directly, but there's no Docker daemon available, and your `public_html`
|
|
is already served by KIT's own web infrastructure — so no web server needs to
|
|
run here at all, only the generator on a schedule.
|
|
|
|
## 1. Install into a venv
|
|
|
|
```bash
|
|
python3 -m venv ~/.venvs/gallery
|
|
~/.venvs/gallery/bin/pip install -e /work/lbogner/ETPlot # path to your clone
|
|
```
|
|
|
|
PyMuPDF (a base dependency) handles PDF→PNG conversion; ImageMagick is not required.
|
|
|
|
## 2. Point a config at your paths
|
|
|
|
Copy/edit `config.lbogner.yaml` from the repo root (already has `web_folder:
|
|
/web/lbogner/public_html/` and placeholder `sources:` — fill in the real
|
|
plot-output directories under `/work/lbogner/...` or `/ceph/...`). Put it
|
|
wherever you like, e.g. `~/gallery/config.lbogner.yaml`, and adjust the path in
|
|
`gallery-generate.service` if you move it.
|
|
|
|
## 3. Install the systemd --user timer
|
|
|
|
```bash
|
|
mkdir -p ~/.config/systemd/user
|
|
cp deploy/systemd/gallery-generate.{service,timer} ~/.config/systemd/user/
|
|
systemctl --user daemon-reload
|
|
systemctl --user enable --now gallery-generate.timer
|
|
```
|
|
|
|
Check status/logs:
|
|
|
|
```bash
|
|
systemctl --user list-timers gallery-generate.timer
|
|
journalctl --user -u gallery-generate.service -f
|
|
```
|
|
|
|
By default a user's systemd instance (and its timers) stops when you log out.
|
|
Enable lingering so it keeps running:
|
|
|
|
```bash
|
|
loginctl enable-linger $USER
|
|
```
|
|
|
|
If lingering isn't permitted on your login node, or `systemctl --user` isn't
|
|
usable there at all, fall back to a crontab entry instead:
|
|
|
|
```
|
|
*/5 * * * * ~/.venvs/gallery/bin/gallery --config ~/gallery/config.lbogner.yaml generate >> ~/gallery-generate.log 2>&1
|
|
```
|
|
|
|
## Why not the Docker Compose stack?
|
|
|
|
`docker-compose.yml` at the repo root (generator + nginx) is for a scenario
|
|
where you control a dedicated VM/server and need to serve the output yourself.
|
|
On the ETP login nodes there's no Docker daemon (Apptainer/Singularity only),
|
|
and `public_html` is already auto-served — running your own nginx there would
|
|
be redundant. It remains a fine option for anyone deploying this on their own
|
|
server.
