Hi everybody,
I made a GitHub action that builds the app inventor, then builds the docker image and pushes it to the docker registry. The server.sh and dockerfile below are for just the frontend and gwt parts except for the build server. To run the build server, the last line of the server.sh needs to be replaced by ant RunLocalBuildServer and the EXPOSE 8888 in dockerfile be replaced with EXPOSE 9990 and the dockerfile needs to be built again.
Add the files below to their respective paths, Dockerfile and server.sh should be in root of the directory.

Dockerfile
FROM openjdk:8
ENV HOME /home/developer
WORKDIR $HOME
COPY . .
RUN echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] http://packages.cloud.google.com/apt cloud-sdk main" | tee -a /etc/apt/sources.list.d/google-cloud-sdk.list && curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key --keyring /usr/share/keyrings/cloud.google.gpg add - && apt-get update -y && apt-get install google-cloud-sdk -y
RUN apt-get install -y ant
RUN curl 'https://storage.googleapis.com/appengine-sdks/featured/appengine-java-sdk-1.9.84.zip' > /tmp/appengine.zip \
&& unzip -d $HOME /tmp/appengine.zip \
&& rm /tmp/appengine.zip \
&& ln -s $HOME/appengine-java-sdk-1.9.84 $HOME/appengine
EXPOSE 8888
CMD chmod 777 server.sh && ./server.sh

#!/bin/bash
set -e
cd appinventor
/home/developer/appengine/bin/dev_appserver.sh --port=8888 --address=0.0.0.0 appengine/build/war/
Now you can deploy that image anywhere, on platforms such as https://railway.app allow you to deploy docker images for free, so go and try that. You can also try the https://ai2.up.railway.app hosted there.
How to deploy?
Simple, just make a new github repo by going to repo.new and add the image name in the dockerfile.
Dockerfile:
FROM your-dockerhub-username/ai2:tagreplace
your-dockerhub-usernamewith the dockerhub username andtagwith the latest github commitshaon your repo where the github action was run.
Deploy Buildserver
Note: its not recommended to deploy the buildserver with environments with low RAM limits as it may fail, tho if you want to still do it, then follow along.
Deploying this on a different environment in the same railway project, gives it a full 1GB RAM and builds may succeed.
To dockerize the buildserver you follow the same GitHub action but with a different Dockerfile and server.sh file. The updated ones for buildserver are given below:
Dockerfile
FROM openjdk:8
ENV HOME /home/developer
WORKDIR $HOME
COPY . .
RUN echo "deb [signed-by=/usr/share/keyrings/cloud.google.gpg] http://packages.cloud.google.com/apt cloud-sdk main" | tee -a /etc/apt/sources.list.d/google-cloud-sdk.list && curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key --keyring /usr/share/keyrings/cloud.google.gpg add - && apt-get update -y && apt-get install google-cloud-sdk -y
RUN apt-get install -y ant
RUN curl 'https://storage.googleapis.com/appengine-sdks/featured/appengine-java-sdk-1.9.84.zip' > /tmp/appengine.zip \
&& unzip -d $HOME /tmp/appengine.zip \
&& rm /tmp/appengine.zip \
&& ln -s $HOME/appengine-java-sdk-1.9.84 $HOME/appengine
EXPOSE 9990
CMD chmod 777 server.sh && ./server.sh
server.sh
#!/bin/bash
set -e
cd appinventor
ant RunLocalBuildServer
