Create a fast running Docker custom action

I am creating a GitHub Docker container action that involves a number of dependencies: Python, Node, PyPI packages, and npm packages. In order to speed up the action I move a lot of the dependency installation from the entrypoint to the Dockerfile. Now my action is running really fast, but takes a really long time to build the action every time.

Is there a way that the action can be pre-built, or do I need to publish my Docker image to a repository somewhere and feed FROM my custom image?

For reference, here is my Dockerfile.

FROM python:3

LABEL "com.github.actions.name"="kedro-action"
LABEL "com.github.actions.description"="A Github Action to run kedro commands"
LABEL "com.github.actions.icon"="it-branch"
LABEL "com.github.actions.color"="black"

LABEL "repository"="http://github.com/WaylonWalker/kedro-action"
LABEL "maintainer"="Waylon Walker <[email protected]>"

RUN apt-get update
RUN apt-get install -y jq

ENV PYENV_ROOT /root/.pyenv
ENV PATH $PYENV_ROOT/shims:$PYENV_ROOT/bin:$PATH
RUN curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash

### INSTALL PYTHON ###
RUN pyenv install 3.7.6
RUN pyenv global 3.7.6
RUN python -m pip install --upgrade pip
RUN pip install kedro
RUN pip install kedro-viz

### INSTALL NODEJS ###
RUN apt-get install curl -y
RUN curl -sL https://deb.nodesource.com/setup_11.x | bash -
RUN apt-get install nodejs -y

### CLONE KEDRO-STATIC-VIZ ###
RUN mkdir ~/build_dir && cd ~/build_dir
RUN git clone https://github.com/WaylonWalker/kedro-static-viz.git
RUN cd kedro-static-viz
RUN npm install -g gatsby-cli
RUN cd kedro-static-viz && npm install && npm audit fix


ADD entrypoint.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]

You can prebuild the Docker image for your action and then in the action.yml file you specify the prebuilt image instead of Dockerfile. See the documentation here.

This is an example for one of my actions that is prebuilt here.

runs:
  using: 'docker'
  image: 'docker://peterevans/dockerhub-description:2.1.0'
