Quando eu instalo o sshpass no alpine linux, ele será instalado e o doc aparecerá se você executá-lo sem argumentos, mas usando qualquer argumento (válido ou inválido) retorna sshpass: Failed to run command: No such file or directory.
É pathed e mesmo ao usar um path absoluto tem o mesmo comportamento. Eu quero usar isso com ansible, mas nem vai funcionar diretamente.
Não consigo encontrar nenhuma informação on-line sobre esse funcionamento ou não para outras pessoas, mas usei os contêineres de outras pessoas e os meus e também não consegui fazê-lo funcionar. https://pkgs.alpinelinux.org/package/v3.3/main/x86/sshpass
$ docker run -it --rm williamyeh/ansible:alpine3 ash
/ # sshpass
Usage: sshpass [-f|-d|-p|-e] [-hV] command parameters
-f filename Take password to use from file
-d number Use number as file descriptor for getting password
-p password Provide password as argument (security unwise)
-e Password is passed as env-var "SSHPASS"
With no parameters - password will be taken from stdin
-P prompt Which string should sshpass search for to detect a password prompt
-v Be verbose about what you're doing
-h Show help (this screen)
-V Print version information
At most one of -f, -d, -p or -e should be used
/ # sshpass hi
sshpass: Failed to run command: No such file or directory
/ # which sshpass
/usr/bin/sshpass
/ # /usr/bin/sshpass

Vale a pena mencionar que o executável ssh subjacente funciona e posso me conectar ao host dessa maneira.
