/bin/bash: Command not found in alpine docker

To add bash using Alpine Package Keeper (APK) use the follow command:

apk updateapk add --no-cache bash

Don't forget set bash as default shell:

apk add --no-cache shadowchsh -s /bin/bashexec /bin/bash

use the package manager, named apk, this way:

% docker run --rm -it alpine /bin/sh/ #/ # apk add --no-cache bashfetch http://dl-cdn.alpinelinux.org/alpine/v3.5/main/x86_64/APKINDEX.tar.gzfetch http://dl-cdn.alpinelinux.org/alpine/v3.5/community/x86_64/APKINDEX.tar.gz(1/5) Installing ncurses-terminfo-base (6.0-r8)(2/5) Installing ncurses-terminfo (6.0-r8)(3/5) Installing ncurses-libs (6.0-r8)(4/5) Installing readline (6.3.008-r4)(5/5) Installing bash (4.3.46-r5)Executing bash-4.3.46-r5.post-installExecuting busybox-1.25.1-r0.triggerOK: 12 MiB in 16 packages/ # which -a bash/bin/bash

There is no /bin/bash in alpine:

$ docker run -i -t alpine/ # ls /bin/bashls: /bin/bash: No such file or directory

Note that there is no make or go neither. So, either you checked their existence in your host instead of in alpine, or you are not using vanilla alpine.
