下载时，“ docker pull redis”卡住了

Question

当我调用“ docker pull redis”时，我得到：

    Using default tag: latest
    latest: Pulling from library/redis
    000eee12ec04: Already exists
    5cc53381c195: Already exists
    48bb7bcb5fbf: Already exists
    ef8a890bb1c2: Already exists
    32ada9c6fb0d: Already exists
