Execution

How to build

bazel build //mysite:mysite

How to execute

How to push image

Change mysite/BUILD.bazel and execute bazel.

bazel run //mysite:push

所感

  • requirements.txtを元にdependenciesを定義できるから、dependency managementはgazelleを使うより楽そう。
pip_import(
    name = "mysite_deps",
    requirements = "//:requirements.txt",
)

load("@mysite_deps//:requirements.bzl", mysite_deps_install = "pip_install")

mysite_deps_install()
  • gcrにpushするのにpython2が必要だけどアプリがpython3じゃないといけなかったりしてて、pythonつらい。toolchainでいい感じに設定できるらしいけど、いまいち動きが分かってない。
load("@bazel_tools//tools/python:toolchain.bzl", "py_runtime_pair")

    name = "python-3.6.8",
    interpreter_path = "~/.pyenv/versions/3.6.8/bin/python3",
