When running the alpine docker container the first time and attempting an openssh install, the following happens:
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] How should openssh be installed?

OpenSSH is a popular SSH implementation for remote encrypted login to a machine. OpenSSH defines sshd as the daemon, and ssh as the client program. The openssh package provides OpenSSH on Alpine Linux.
To install Docker on Alpine Linux, run apk add --update docker openrc. The Docker package is available in the Community repository. Therefore, if apk add fails because of unsatisfiable constraints error, you need to edit the /etc/apk/repositories file to add (or uncomment) a line.
Install OpenSSH using Windows SettingsFirst, click the Start button, then click Settings. Next, click the 'Apps' category. Click the 'Add a feature' '+' at the top of the 'Optional features' window. Scroll down to 'OpenSSH Client', place a checkmark next to it and click the 'Install' button.
Run apk update first. The below paste contains a complete example:
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 / # apk add openssh (1/3) Installing openssh-client (7.1_p2-r0) (2/3) Installing openssh-sftp-server (7.1_p2-r0) (3/3) Installing openssh (7.1_p2-r0) Executing busybox-1.24.1-r7.trigger OK: 8 MiB in 14 packages If you love us?
