Updating Strapi Docker package.json

I'm in the process of learning about Docker by trying to containerify a Strapi CMS. The default Docker image (https://github.com/strapi/strapi-docker) works well enough as a starting point, but I'm trying to add a couple packages to the Strapi instance for my needs (adding in Azure storage account support using https://www.npmjs.com/package/strapi-provider-upload-azure-storage). As I'm new to Docker, I'm having a hard time figuring how to make the container install that package as part of the Docker run process.

I see that the strapi/base image Dockerfile contains this line referencing a package.json file:

COPY ./package.json ./

I'm assuming that's where I would add a reference to the packages I'm wanting to install so that later on they are installed by npm, but I'm not sure where that package.json file is located, let alone how to modify it.

Any help on figuring out how to install that package during the Docker run process is greatly appreciated!

package.json npm strapi docker

I figured out that strapi-docker uses a script to build images and not just the Docker files in the repo (bin/build.js). I also discovered that docker-entrypoint.sh is where the dependency installation is happening, so I added a couple of npm install statements after the check for the node_modules directory. Doing this allowed me to successfully add the desired packages to my Docker container.

I followed some of the advice from the Docker team here:

After performing the initial setup with docker-compose and the strapi/strapi image, I was able to install additional dependencies directly inside the container using docker-compose run <service name> yarn add <package>.

I opted for this route since I was having trouble installing the sharp library - it has different dependencies/binaries for Linux and Mac OS. This approached worked well for me, but the downside is that you can't mount your node_modules folder as a volume and it may take a little longer to install packages in the container.
