Deterministic builds with nodejs + bazel + docker

Simple helloworld about how to build nodeJS deterministic container images using bazel.

This similar to

• Deterministic builds with go + bazel + grpc + docker

except that the application is a simple http client/server (i.,e not gRPC)

(The reason for this repo is i needed to generate a nodejs container app using bazel and didn't find the documentation that straightforward (i.,e building nodejs apps in bazel has several nuances).

you should expect the following image hashes if using the same baze and node toolchains

• server: node_server@sha256:3bc3eacfeffcf4c656e609131a0c26ba4f9f7469df6dcf048b0e433b31038890
• client: node_client@sha256:8174e52e2cb837e9bc9b5299c5e0ec6b98b10882f05778ff83bdcc702f86d240

Anyway, for reference, see:

• Building deterministic Docker images with Bazel
• Create Container images with Bazel
• rules_docker

Setup

You'll need bazel ofcourse and docker too to actually run the image locally if you want to.

You should be able to use any bazel version but i used

$ bazel verson
    Build label: 5.3.2

Server

To build the server and run locally

cd server/
bazel run :server

To build and run the container image

bazel run :server_image
docker run -p 8080:8080 us-central1-docker.pkg.dev/builder-project/repo1/node_server:server_image

with google cloud build

gcloud builds submit .

export PROJECT_ID=$(gcloud config list --format="value(core.project)")
docker pull us-central1-docker.pkg.dev/$PROJECT_ID/repo1/node_server

Client

To build the client and run locally

cd client/
bazel run :client

To build and run container image

bazel run :client_image
docker run --net=host us-central1-docker.pkg.dev/builder-project/repo1/node_client:client_image

with google cloud build

gcloud builds submit .

export PROJECT_ID=$(gcloud config list --format="value(core.project)")
docker pull us-central1-docker.pkg.dev/$PROJECT_ID/repo1/node_server
