Developers need to set the registry and log in to ensure npm is able to publish and install packages. npmrc file, it'll be kept in the commit history - to clean your secret up entirely make sure to squash them.It is common for companies to have their own private npm registries to store proprietary code. This will take your current NPM_TOKEN environment variable, and will build the Docker image using it, so you can run npm install inside your container as the current logged in user! That file should contain the following content: ///:_authToken=$. We'll use the slightly confusingly named ARG parameter.Ī complete example that will allow us to use -build-arg to pass in our NPM_TOKEN requires adding a.

We have to take advantage of a different way of passing environment variables to Docker, available since Docker 1.9. However, this doesn't work as you would expect, because you want the npm install to occur when you run docker build, and in this instance, ENV variables aren't used, they are set for runtime only.

In order to install private packages, you may think that we could just add a line before we run npm install, using the ENV parameter: ENV NPM_TOKEN=00000000-0000-0000-0000-000000000000

Which will use the RisingStack Alpine Node.JS Docker image, copy the package.json into our container, installs dependencies, copies the source files and runs the start command as specified in the package.json. If you had the following Dockerfile: FROM risingstack/alpine:3.3-v4.3.1-3.0.1 If it doesn't, here we'll look at the problems with this workflow when running npm install inside a Docker container. If that works with your system, then, perfect. If this is the workflow you need, please read the CI Server Config doc. The Getting an Authentication Token should help you generate that token. If you're using npm private packages in an environment where you're not directly able to log in, such as inside a CI Server or a Docker container, you'll need to get and export an npm token as an environment variable. If you've read through Working with private packages, you'll know that in order to use private packages, you need to be logged in to npm via the npm CLI.
