如何在 cloudbuild.yaml 中使用 Kaniko？

问题描述

我刚刚了解到，可以通过使用 Kaniko 缓存来加快 Google Cloud 构建中的构建过程。我查看了文档，它提供了一个小例子。但是，我不确定如何在我的用例中应用它。我基本上是将 Nuxt 应用程序推送到我的 Github 存储库中，并且每次推送时云都会构建它。文档示例说我们需要用 cloud-builders/docker 替换 kaniko-project/executor:latest。下面是我的cloudbuild.yaml

的片段

steps:
# Create .npmrc file from Fontawesome secret
- name: gcr.io/cloud-builders/gcloud
  entrypoint: 'bash'
  args: [ '-c','gcloud secrets versions access latest --secret=fontawesome > .npmrc' ]
# Build the container image
- name: 'gcr.io/cloud-builders/docker'
  args: ['build','-t','gcr.io/PROJECTNAME/IMAGENAME:$COMMIT_SHA','.']
# Push the image to Container Registry
- name: 'gcr.io/cloud-builders/docker'
  args: ['push','gcr.io/PROJECTNAME/IMAGENAME:$COMMIT_SHA']

Kaniko 文档说我需要以下内容：

steps:
- name: 'gcr.io/kaniko-project/executor:latest'
  args:
  - --destination=gcr.io/$PROJECT_ID/image
  - --cache=true
  - --cache-ttl=XXh

这是我尝试过的（但不确定是否应该这样）：

steps:
    # Create .npmrc file from Fontawesome secret
    - name: gcr.io/cloud-builders/gcloud
      entrypoint: 'bash'
      args: [ '-c','gcloud secrets versions access latest --secret=fontawesome > .npmrc' ]
    # Build the container image
    - name: 'gcr.io/kaniko-project/executor:latest'
      args: ['--destination=gcr.io/$PROJECT_ID/image','--cache=true','--cache-ttl=6h','build','.']
    # Push the image to Container Registry
    - name: 'gcr.io/kaniko-project/executor:latest'
      args: ['--destination=gcr.io/$PROJECT_ID/image','push','gcr.io/PROJECTNAME/IMAGENAME:$COMMIT_SHA']

解决方法

Kaniko 没有推送和构建命令。当您在 cloudbuild.yaml 中将其指定为构建步骤时，它将隐式执行此操作（构建和推送）。

一个例子是：

steps:
  # Build the container image and push it with Kaniko
  - name: 'gcr.io/kaniko-project/executor:latest'
    args:
      [
        "--dockerfile=<DOCKER-FILE-DIST>","--context=dir://<BUILD_CONTEXT>","--cache=true","--cache-ttl=6h","--destination=gcr.io/$PROJECT_ID/hello:$COMMIT_SHA"
      ]
  # Deploy image to Cloud Run
  - name: "gcr.io/cloud-builders/gcloud"
    args:
      - "run"
      - "deploy"
      - "hello"
      - "--image"
      - "gcr.io/$PROJECT_ID/hello:$COMMIT_SHA"
      - "--region"
      - "us-central1"
      - "--platform"
      - "managed"
