# docker-sigal
# sigal Docker image
Docker image based on nginx official one for [sigal](http://sigal.saimon.org/en/latest/) gallery.
This project is a fork of the [remche/docker-sigal](https://github.com/remche/docker-sigal) project.
The Docker image, based on nginx official one, includes the code for running a [sigal](http://sigal.saimon.org/en/latest/) gallery website.
Run with :
Default configuration use the galleria theme, keep original and put gallery in /usr/share/nginx/html. You can use a docker volume if you want it permanent
## Exposed volumes
docker run -p 80:80 -v /path/to/your/pictures/:/pictures --name sigal-ct -d remche/docker-sigal
- `/pictures` : Where your data files are stored.
- `/config` : Where you can find and edit the configuration file
- `/themes` : Where you can store external themes
- `/plugins` : Where you can store external plugins
- `/usr/share/nginx/html` : Where the generated HTML code is stored.
Decalring it as a volume allows for making it permanent
docker run command setting all these volumes
```bash
mkdir -p pictures config themes plugins html
docker run -p 8888:80 \
-v ./pictures:/pictures \
-v ./config:/config \
-v ./themes:/themes \
-v ./plugins:/plugins \
-v ./html:/usr/share/nginx/html \
-n sigal-server \
-d zafacs/sigal
```
## Environment variables
- `JPEG_QUALITY`: set the default quality for *JPEG* conversion.
Option to be added to the docker run command :
- `HTPASSWD`: Allows for setting a basic authentication in `htpasswd`.
You might then use SSL with
[nginx-proxy](https://hub.docker.com/r/jwilder/nginx-proxy/).
- `CRONJOB`: Allows to define a `cron` task in the docker container that will
update the website. The value of the CRONJOB variable is a text
constituted of 5 items defining at witch time the update has to be done.
The syntax follows the [crontab syntax](https://tecadmin.net/crontab-in-linux-with-20-examples-of-cron-schedule/)
+ `* * * * *` : The site is updated every minute.
+ `10 * * * *` : The site is updated every hour at the $10^{th}$ minute.
+ `*/15 * * * *` : The site is updated every 15 minutes.
Default configuration use the galleria theme, keep original and put gallery in /usr/share/nginx/html. You can use a docker volume if you want it permanent :
```bash
docker run -p 8888:80 \
-v ./pictures:/pictures \
-v ./config:/config \
-v ./themes:/themes \
-v ./plugins:/plugins \
-v ./html:/usr/share/nginx/html \
-n sigal-server \
-e JPEG_QUALITY=80 \
-e HTPASSWD='foo:$apr1$odHl5EJN$KbxMfo86Qdve2FH4owePn.' \
-e CRONJOB='*/15 * * * *' \
-d zafacs/sigal
```
docker run -p 80:80 -v /path/to/your/pictures/:/pictures -v sigal-html:/usr/share/nginx/html --name sigal-ct -d remche/docker-sigal
You can use the following command to force the regeneration of gallery :
If you want to override this conf, you can use your own sigal.conf.py :
docker run -p 80:80 -v /path/to/your/pictures/:/pictures -v/path/to/your/sigal.conf.py:/opt/sigal.conf.py --name sigal-ct -d remche/docker-sigal
You can set a basic authentication in htpasswd format by setting HTPASSWD env variable :
docker run -p 80:80 -v /path/to/your/pictures/:/pictures -e HTPASSWD='foo:$apr1$odHl5EJN$KbxMfo86Qdve2FH4owePn.' --name sigal-ct -d remche/docker-sigal
You might then use SSL with [nginx-proxy](https://hub.docker.com/r/jwilder/nginx-proxy/).
You can use the following command to regenerate gallery :
docker exec sigal-ct sigal build
Using a cron or incron to run it is a good way to keep your gallery up to date.
```bash
docker exec sigal-ct build_sigal
```
