docker-generate-npm-authtoken

Input credentials, output auth token.

Why

For some reason, the npm login command is interactive, and this causes problems when you need to call the command from non-interactive shells such as in a Dockerfile. By using the bravissimolabs/generate-npm-authtoken you can generate an auth token. Output this to ~/.npmrc and you are now authenticated with npm and can npm install private npm modules.

Usage

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    bravissimolabs/generate-npm-authtoken

If you want to save output to ~/.npmrc where it doesn't exist, you can simply redirect the output.

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    bravissimolabs/generate-npm-authtoken \
    > ~/.npmrc

Bear in mind that this will overwrite an existing .npmrc, so if you don't want to do that, append it instead with >>. Note: when there are multiple auth tokens in .npmrc, npm uses the last occurrence.

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    bravissimolabs/generate-npm-authtoken \
    >> ~/.npmrc

Using a different registry

If you need to use a different registry, pass the environment variable NPM_REGISTRY through, but make sure it has the protocol specified, i.e. NPM_REGISTRY=https://skimdb.npmjs.com/registry, NOT NPM_REGISTRY=skimdb.npmjs.com/registry.

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    -e NPM_REGISTRY=$NPM_REGISTRY \
    bravissimolabs/generate-npm-authtoken \
    >> ~/.npmrc

Using a different registry with a scope

You can extend your registry login by adding a scope.

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    -e NPM_REGISTRY=$NPM_REGISTRY \
    -e NPM_SCOPE=$YOUR_NPM_SCOPE
     bravissimolabs/generate-npm-authtoken \
     >> ~/.npmrc

Using the 2FA option

If your account has 2FA enabled you can pass the code.

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    -e NPM_REGISTRY=$NPM_REGISTRY \
    -e NPM_SCOPE=$YOUR_NPM_SCOPE \
    -e TWO_F_A_CODE=$YOUR_TWO_F_A_CODE \
     bravissimolabs/generate-npm-authtoken \
     >> ~/.npmrc

Just have in mind you should pass a VERY FRESH token to give the script enough time to authenticate the account while the code is valid.
