我试图使用Fabric运行docker-compose,但是当我使用Fabric运行docker-compose up命令时,出现以下错误:

[52577] Failed to execute script docker-compose

KeyError: 'PATH'
Failed to up the env

当我从终端运行docker-compose时,它工作正常。

@task
def up(c):
    if c.run('docker-compose up', warn=True).failed:
        print ("Failed to up the env")

答案 0 :(得分:1)

正如我的评论所建议的,似乎docker-composer up至少需要执行build时,需要设置PATH环境变量。为了解决这个问题,我刚刚将PATH从当前会话转发到子进程(对不起,PHP!):

$compose = new Process( 'docker-compose up -d', '', [
    'VOLUME' => getcwd(),
    'PATH' => getenv( 'PATH' ),
] );
