Linux 在 Alpine Docker 容器上安装 OpenSSH

发布于02月29日

第一次运行alpine docker容器并try openssh安装时，会发生以下情况:

ole@T:~$ docker run -it --rm alpine /bin/ash
/ # apk add openssh
WARNING: Ignoring APKINDEX.d3812b7e.tar.gz: No such file or directory
WARNING: Ignoring APKINDEX.bb2c5760.tar.gz: No such file or directory
ERROR: unsatisfiable constraints:
  openssh (missing):
    required by: world[openssh]

openssh应该如何安装？

推荐答案

先跑apk update.下面的粘贴包含一个完整的示例:

    ole@T:~$ docker run -it --rm alpine /bin/ash
    / # apk update
    fetch http://dl-4.alpinelinux.org/alpine/v3.3/main/x86_64/APKINDEX.tar.gz
    fetch http://dl-4.alpinelinux.org/alpine/v3.3/community/x86_64/APKINDEX.tar.gz
    v3.3.1-97-g109077d [http://dl-4.alpinelinux.org/alpine/v3.3/main]
    v3.3.1-59-g48b0368 [http://dl-4.alpinelinux.org/alpine/v3.3/community]
    OK: 5853 distinct packages available
