我正在尝试使用GCB部署我的项目，但遇到了一些麻烦。
代码：cloudbuild.yml
steps:
- name: 'ngocquyhoang/google-cloud-build:wordpress'
args: ['deploy']
env:
- 'BUILD_USER=$_USER'
- 'BUILD_HOST=$_HOST'
- 'BUILD_KEY=$_KEY'
- 'BUILD_PATH=$_PATH'
我的Dockerfile是构建ngocquyhoang/google-cloud-build:wordpress映像：
FROM alpine:3.10.2
MAINTAINER Hoang Ngoc Quy <ngocquyhoang3112@gmail.com>
RUN apk update
RUN apk upgrade
RUN apk add --no-cache rsync
RUN apk add --no-cache openssh
COPY docker-entrypoint.sh /script/docker-entrypoint.sh
WORKDIR /app/deploy
ENTRYPOINT ["/bin/sh", "/script/docker-entrypoint.sh"]
CMD ["deploy"]
文件docker-entrypoint.sh
#!/bin/bash
mkdir -p /root/.ssh
ssh-keyscan -H "$BUILD_HOST" >> /root/.ssh/known_hosts
echo -e $BUILD_KEY >> /root/.ssh/id_rsa
chmod 400 /root/.ssh/id_rsa
rsync --progress -avzh --exclude='.git/' -e "ssh -i /root/.ssh/id_rsa" --rsync-path="sudo rsync" . $BUILD_USER@$BUILD_HOST:$BUILD_PATH
并生成日志：
