我基本上试图让Flask-migrate的shell使用Flask app context执行heredoc
以下是我试图在我的bash脚本中运行的命令
$ docker exec -it mycontainer ./manage shell <<-EOF
# shell commands to be executed
EOF
尝试执行上述命令时,我得到:
cannot enable tty mode on non tty input
这是管理文件:
#!/usr/bin/env python
from middleware import create_app, config
from middleware.models import db
from flask.ext.script import Manager
from flask.ext.migrate import Migrate, MigrateCommand
app = create_app(config)
migrate = Migrate(app, db)
manager = Manager(app)
manager.add_command('db', MigrateCommand)
if __name__ == '__main__':
manager.run()
我的问题是有没有办法将像heredoc这样的命令传递给shell?
答案 0 :(得分:8)
从-t
命令中删除docker exec
选项以删除附加的pseudo-TTY
或使用--tty=false
:
docker exec -i mycontainer ./manage shell <<-EOF
# shell commands to be executed
EOF
否则:
docker exec -i --tty=false mycontainer ./manage shell <<-EOF
# shell commands to be executed
EOF
