Modifying docker image to work with gitlab-ci - docker

Question

I have a gitlab pages site that is built inside a docker container. I found a base image that contains 95% of what I want. With my old ci, I was installing extra packages before the build step. I want to create a new image with these packages installed, and use that image. I was able to build and run this image, but it no longer runs in gitlab actions. I'm not sure why.
Git repo: https://gitlab.com/hybras/hybras.gitlab.io
CI Config:
image: klakegg/hugo:asciidoctor-ci # old
image: registry.gitlab.com/hybras/hybras.gitlab.io # new
variables:
GIT_SUBMODULE_STRATEGY: recursive
SSHPASS: $SSHPASS
pages:
script:
- gem install asciidoctor-html5s # remove these package installs in the new version
- apk add openssh sshpass # remove these package installs in the new version
- hugo
- sshpass -p $SSHPASS scp -r public/* $HOST_AND_DIR
artifacts:
paths:
- public
only:
- master
Successful Job: Installs the packages, builds the site, scp's it to my mirror
Dockerfile:
FROM klakegg/hugo:asciidoctor
RUN gem install asciidoctor-html5s --no-document \
&& apk --no-cache add openssh sshpass
CMD hugo
Failed CI Run: Error: unknown command "sh" for "hugo"

Answer 1

As it can be seen in your pipeline, there is an error:
Error: unknown command "sh" for "hugo"
It means that you haven't hugo installed on the image you've been using. In order to solve this problem, you can use the official docker image of Hugo. For this purpose, you have to use its image or install hugo on the image you are using.
1. Using Hugo image:
Add the following lines to the stage you want to use hugo:
<pipeline_name>:
image: klakegg/hugo
2. Install Hugo on existing image
Check out this page to find out how to install the Hugo on different distribution of your base image.
For example you can install Hugo on ubuntu using the following command:
<pipeline_name>:
before_scripts:
- sudo apt-get install hugo
3. Install Hugo in your Dockerfile
RUN apk add hugo # Or something like this!
