我是Bazel的新手，无法找到有关为Node.Js构建Docker映像的足够资源。
所以我有一个用Typescript编写的Node.js应用程序，具体取决于其他两个Typescript包。我的目标是构建一个Docker映像，之后可以将其部署到Kubernetes。
我已经在工作Dockerfile：
FROM node:10-alpine
WORKDIR /usr/app/src
COPY package.json .
COPY yarn.lock .
COPY ./packages ./packages
COPY ./services/gateway ./services/gateway
RUN yarn install
COPY ./tsconfig.settings.json ./
COPY ./tsconfig.json ./
WORKDIR /usr/app/src/services/gateway
CMD yarn start
但是我正在努力通过Bazel复制它。

答案 0 :(得分：1)
我认为一个问题是，您正在呼叫yarn_install，而 bazel 正在寻找npm_install。这就是它找不到
因此，您要么必须使用npm_install，要么通过更改来加载yarn_install规则
load("@build_bazel_rules_nodejs//:defs.bzl", "node_repositories", "npm_install")至
load("@build_bazel_rules_nodejs//:defs.bzl", "node_repositories", "yarn_install")中的WORKSPACE.bazel
另一个问题可能是http_archive被加载了两次。
答案 1 :(得分：1)
您无法确定目标，因为两个规则都被称为“网关”。将nodejs_image规则的名称更改为'foo'，然后尝试bazel build //...
尝试在构建文件中使用此导入：
load("@npm_bazel_typescript//:index.bzl", "ts_library")
，取自rules_nodejs示例存储库：
https://github.com/bazelbuild/rules_nodejs/blob/master/examples/app/BUILD.bazel
还要确保您的package.json具有以下dev依赖项。
"devDependencies": {
"@bazel/bazel": "latest",
"@bazel/ibazel": "latest",
"@bazel/buildifier": "latest",
"@bazel/typescript": "latest",
"typescript": "~3.4.0"
},
此外，在您的WORKSPACE文件中，尝试复制示例的WORKSPACE文件：
http_archive(
name = "build_bazel_rules_nodejs",
sha256 = "16fc00ab0d1e538e88f084272316c0693a2e9007d64f45529b82f6230aedb073",
urls = ["https://github.com/bazelbuild/rules_nodejs/releases/download/0.42.2/rules_nodejs-0.42.2.tar.gz"],
)
load("@build_bazel_rules_nodejs//:index.bzl", "yarn_install")
yarn_install(
name = "npm",
package_json = "//:package.json",
yarn_lock = "//:yarn.lock",
)
load("@npm//:install_bazel_dependencies.bzl", "install_bazel_dependencies")
install_bazel_dependencies()
load("@npm_bazel_typescript//:index.bzl", "ts_setup_workspace")
ts_setup_workspace()
https://github.com/bazelbuild/rules_nodejs/blob/master/examples/app/WORKSPACE
更新：
请参阅构建ts_library和nodejs_image的最小存储库： https://github.com/mancini0/minimal_bazel_docker_nodejs
请注意，您的工作区文件的yarn_install规则应指向您的package.json，yarn.lock等。如果它们位于项目的根目录，则应为“：package.json”，否则应为“ // mysubproject：package”。 json” /“ /// mysubproject：yarn.lock”（如果它们位于mysubproject中。）
