[英]Expand a Bazel rule output's directory into a flat output of another rule
我正在嘗試將 package 捆綁包上傳到 Google Cloud。 我有一個來自我所做的 angular 構建的pkg_web
的 output,如果我傳遞到我正在生成的這個自定義規則中,它是一個File
object 的目錄,它是文件的目錄。 我生成的自定義規則采用 app.yaml 等,以及捆綁包和上傳。
但是,捆綁包變成了一個目錄,我需要擴展該目錄的文件以在命令的根目錄中上傳。
例如:
- bundle/index.html <-- bundle directory
- bundle/main.js
- app.yaml
我需要:
- index.html
- main.js
- app.yaml
我的規則:
deploy(
name = "deploy",
srcs = [":bundle"] <-- pkg_web rule,
yaml = ":app.yaml"
)
規則實現:
def _deploy_pkg(ctx):
inputs = []
inputs.append(ctx.file.yaml)
inputs.extend(ctx.files.srcs)
script_template = """
#!/bin/bash
gcloud app deploy {yaml_path}
"""
script = ctx.actions.declare_file("%s-deploy" % ctx.label.name)
ctx.actions.write(script, script_content, is_executable = True)
runfiles = ctx.runfiles(files = inputs, transitive_files = depset(ctx.files.srcs))
return [DefaultInfo(executable = script, runfiles = runfiles)]
謝謝你的想法!
似乎有點過分,但我結束了使用自定義 shell 命令來完成此操作:
def _deploy_pkg(ctx):
inputs = []
out = ctx.actions.declare_directory("out")
yaml_out = ctx.actions.declare_file(ctx.file.yaml.basename)
inputs.append(out)
ctx.actions.run_shell(
outputs = [yaml_out],
inputs = [ctx.file.yaml],
arguments = [ctx.file.yaml.path, yaml_out.path],
progress_message = "Copying yaml to output directory.",
command = "cp $1 $2",
)
for f in ctx.files.srcs:
if f.is_directory:
ctx.actions.run_shell(
outputs = [out],
inputs = [f],
arguments = [f.path, out.path],
progress_message = "Copying %s to output directory.".format(f.basename),
command = "cp -a -R $1/* $2",
)
else:
out_file = ctx.actions.declare_file(f.basename)
inputs.append(out_file)
ctx.actions.run_shell(
outputs = [out_file],
inputs = [f],
arguments = [f.path, out_file.path],
progress_message = "Copying %s to output directory.".format(f.basename),
# This is what we're all about here. Just a simple 'cp' command.
# Copy the input to CWD/f.basename, where CWD is the package where
# the copy_filegroups_to_this_package rule is invoked.
# (To be clear, the files aren't copied right to where your BUILD
# file sits in source control. They are copied to the 'shadow tree'
# parallel location under `bazel info bazel-bin`)
command = "cp -a $1 $2",
)
