docker - 来自文件的 Google Cloud Build Docker build-arg

Question

我在使用 Google Cloud Build 时遇到问题。我无法通过 cloudbuild.yaml 将 key 传递给 docker

谷歌构建文件.yaml:

- name: 'gcr.io/cloud-builders/gcloud'
  args:
  - kms
  - decrypt
  - --ciphertext-file=A.enc
  - --plaintext-file=/root/.ssh/id_rsa
  - --location=global
  - --keyring=keyringxxx
  - --key=keyxxx
  volumes:
  - name: 'ssh'
    path: /root/.ssh
- name: 'gcr.io/cloud-builders/docker'
  args: [
    'build', '.',
    '-t', 'gcr.io/$PROJECT_ID/xxx:latest',
    '--build-arg', 'READ_KEY=`cat /root/.ssh/id_rsa`'
  ]
  volumes:
  - name: 'ssh'

docker 文件:

FROM golang:1.11 AS builder

ARG READ_KEY
RUN mkdir -p ~/.ssh &&  \
    echo "$READ_KEY" > ~/.ssh/id_rsa && \
    chmod 0600 ~/.ssh/id_rsa && \
    ssh-keyscan github.com >> /root/.ssh/known_hosts && \
    git config --global url.ssh://git@github.com/XXXX.insteadOf https://github.com/XXXX

......

上面的代码失败了。 cat 不起作用。

.ssh 目录需要有正确的权限

RUN mkdir -m 700 -p ~/.ssh &&
