This docker container will take your source Gatsby site files and output the deployment-ready static site files pulling from and writing to your desired directories. These directories are configurable from docker compose.
In order to run this container you will need to have Docker and docker-compose installed on your system.
Run git clone https://gitea.bnolet.me/brandon/gatsby-builder.git to copy all the files to your local machine.
cd gatsby-builder to change into the proper directory.
Create a file named .env and put inside the following values:
USERID=<your-uid>
GROUPID=<your-gid>
You can find these values by entering id -u and id -g in your terminal. This is to ensure the outputted files are accessible to you, the user.
Modify docker-compose.yml to have the ./src and ./public volumes point to your desired folder. For example, if your source files are located in /home/user/hello-world then that is what you would set the source volume to: - /home/user/hello-world:/src. You can set the /public directory to be mapped to a host folder in a similar fashion. The public folder is that which will hold the static site files (html, css, js).
Once you've set up your environment, simply run docker-compose up from the gatsby-builder directory in which the modified docker-compose.yml file resides. The static site files will be deposited in your target folder and should be fully accessible to you.
