With this option you also should use  --silent  to suppress the progress bar. $ curl - v -- silent https :// google . com / -- stderr - | grep expire * expire date : 2015 - 09 - 01 00 : 00 : 00 GMT

First let's add some key values into our vault. vault write secret/ssh/user1 password="abc123" Then you can check it by reading: vault read secret/ssh/user1 To allow salt to access your secrets you must firstly create a policy as follows: salt-policy.hcl [code] path "secret/*" { capabilities = ["read", "list"] } path "auth/*" { capabilities = ["read", "list","sudo",...
