通过自定义podTemplate升级maven和jdk，同时按照文档修改了Jenkins配置文件，也登录Jenkins重新加载了
- maven构建问题解决了
- 但是docker打包镜像时提示无docker这个命令
- docker build -f Dockerfile -t 192.168.3.142:8082/library/finai-demo-devops-api:SNAPSHOT-master-9 .
/home/jenkins/agent/workspace/ch_finai-demo-devops-cicd_master@tmp/durable-6b21eb3a/script.sh: 1: /home/jenkins/agent/workspace/ch_finai-demo-devops-cicd_master@tmp/durable-6b21eb3a/script.sh: docker: not found
script returned exit code 127
这种问题一般要怎么排查
打包的dockerfile如下
