I'm trying to run my GitHub Page which is using Jekyll locally on my Windows machine (code of my page).
The Jekyll config _config.yml references the following plugins:
# all the other Jekyll settings
plugins:
- jekyll-seo-tag
- jekyll-sitemap
- jemoji
I follow the official manual from here and created the following docker-compose.yml:
version: '2.2'
services:
jekyll:
image: jekyll/jekyll:3.8
command: >
sh -c "gem install jekyll-seo-tag jekyll-sitemap jemoji &&
jekyll build &&
jekyll serve --watch --force_polling --verbose"
ports:
- 4000:4000
volumes:
- .:/srv/jekyll
As you can see, at first I have to manually install all dependencies (which are specified in the plugins section of _config.yml).
When reducing the command to jekyll serve (as described in the docs), the following error occurs:
mu88githubio-jekyll-1 | ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-linux-musl]
mu88githubio-jekyll-1 | Configuration file: /srv/jekyll/_config.yml
mu88githubio-jekyll-1 | Dependency Error: Yikes! It looks like you don't have jekyll-seo-tag or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- jekyll-seo-tag' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
mu88githubio-jekyll-1 | jekyll 3.8.6 | Error: jekyll-seo-tag
mu88githubio-jekyll-1 exited with code 1
The docs also mention the command bundle update, but this gives me:
mu88githubio-jekyll-1 | Could not locate Gemfile
mu88githubio-jekyll-1 exited with code 10
What bothers me with my current "solution" is that I have to specify the dependencies/plugins twice, both in docker-compose.yml and _config.yml.
Is it possible to get rid of this redundancy and make the Jekyll Docker image restore the necessary gems automatically when using jekyll serve and using _config.yml?
Thanks and have a great weekend!
