The regular workflow of docker is: first docker create, then docker start. What make me confused are:
Question 1
docker create has an option -a to specify which of stdin, stdout, stderr are attached to the container. docker start also has the same option.
What's the difference? If docker create specified -a stderr only, can docker start specify -a stdout in addition?
Question 2
docker create has an option -i. docker start also has the same option.
What's the difference? If docker create doesn't specified -i, can docker start specify -i?
