Automated Dependency Updates for Bazel Module

Categories: bazel

Renovate supports updating Bazel Module dependencies.

File Matching

By default, Renovate will check any files matching the following regular expression: (^|/|\.)MODULE\.bazel$.

For details on how to extend a manager's fileMatch value, please follow this link.

Supported datasources

This manager supports extracting the following datasources: bazel, docker, github-tags, maven.

Default config

{
  "fileMatch": [
    "(^|/|\\.)MODULE\\.bazel$"
  ]
}

Additional Information

The bazel-module manager can update Bazel module (bzlmod) enabled workspaces.

Maven

It also takes care about maven artifacts initalized with bzlmod. For simplicity the name of extension variable is limited to maven*. E.g.:

maven = use_extension("@rules_jvm_external//:extensions.bzl", "maven")
maven_1 = use_extension("@rules_jvm_external//:extensions.bzl", "maven")

Both install and artifact methods are supported:

maven.install(
    artifacts = [
        "org.seleniumhq.selenium:selenium-java:4.4.0",
    ],
)

maven.artifact(
    artifact = "javapoet",
    group = "com.squareup",
    neverlink = True,
    version = "1.11.1",
)

Docker

Similarly, it updates Docker / OCI images pulled with oci_pull.

Note that the extension must be called oci:

oci = use_extension("@rules_oci//oci:extensions.bzl", "oci")

oci.pull(
    name = "nginx_image",
    digest = "sha256:287ff321f9e3cde74b600cc26197424404157a72043226cbbf07ee8304a2c720",
    image = "index.docker.io/library/nginx",
    platforms = ["linux/amd64"],
    tag = "1.27.1",
)
