Build a Docker image for a workspace.
Install the latest plugin.
yarn plugin import https://github.com/Dcard/yarn-plugins/releases/latest/download/plugin-docker-build.js
The following is a basic example of Dockerfile
.
FROM node:12-alpine AS builder
# Install dependencies for building native libraries
RUN apk add --update git openssh-client python make gcc g++
WORKDIR /workspace
# docker-build plugin copies everything needed for `yarn install` to `manifests` folder.
COPY manifests ./
RUN yarn install --immutable
# You can delete the cache folder after `yarn install` is done.
RUN rm -rf .yarn/cache
FROM node:12-alpine
WORKDIR /workspace
# Copy the installed dependencies from the previous stage.
COPY --from=builder /workspace ./
# docker-build plugin runs `yarn pack` in all workspace dependencies and copies them to `packs` folder.
COPY packs ./
CMD yarn workspace @foo/bar start
This command will build a efficient Docker image which only contains production dependencies for the specified workspace.
You have to create a Dockerfile
in your workspace or your project. You can also specify the path to Dockerfile using the -f, --file
option.
Additional arguments can be passed to docker build
directly, please check the Docker docs for more info: https://docs.docker.com/engine/reference/commandline/build/
Example:
yarn docker build @foo/bar
yarn docker build @foo/bar -t image-tag
yarn docker build --copy secret.key --copy config.json @foo/bar
Path to Dockerfile
. Default to the Dockerfile in the workspace or the project.
Copy additional files to a Docker image. This is useful for secret keys or configuration files. The files will be copied to manifests
folder. The path can be either a path relative to the Dockerfile or an absolute path.
