由于环境变量 : = 无效，Jenkins 管道中的 Docker 无法运行

Question

我正在尝试在 jenkins 管道中运行一个 docker 容器，如下所示:
agent {
docker {
image 'indiehosters/git'
reuseNode true
}
}

但管道无法运行。运行 docker 容器时，似乎设置了无效的环境变量。

我正在使用 Jenkins 2.65 版，Docker 管道插件 1.11，管道插件 2.5

来自 Jenkins 控制台的堆栈跟踪:
java.io.IOException: Failed to run image 'indiehosters/git'. Error: invalid argument "=" for e: invalid environment variable: =
See 'docker run --help'.

好的解决了它。

基本上，Jenkins 中设置了一个空的环境变量。删除了空变量，它起作用了!
