# How to use?
In your `.gitlab-ci.yml` file add the following line (make sure `r3` is written in lower-case):

```
image: git-r3lab.uni.lu:4567/r3/docker/jekyll-lcsb:latest

# or, if you want to use legacy (or other versions) 
image: git-r3lab.uni.lu:4567/r3/docker/jekyll-lcsb:0.1
```

For the reproducibility, it's good if you pin the version to a specific tag, e.g. `1.3` instead of `latest`.

# How to build and push to the repository?
It is handled by gitlab-CI automatically (see `.gitlab-ci.yml`) when you tag the commit.

Anyway, if you'd like to do it yourself, perform these steps:

Login to gitlab registry (you can generate the token to login with https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html).

```
docker login git-r3lab.uni.lu:4567
```

Then, build the image:

```
# replace `new_tag` with e.g. 1.3, and don't forget the dot...
docker build -t git-r3lab.uni.lu:4567/r3/docker/jekyll-lcsb:new_tag .  # ...there
docker build -t git-r3lab.uni.lu:4567/r3/docker/jekyll-lcsb:latest .
```

Publish in repository:

```
docker push git-r3lab.uni.lu:4567/r3/docker/jekyll-lcsb
```
