Clarify if `ssh_timeout` and `ssh_handshake_attempts` are mutually exclusive #217
ssh_timeout (duration string | ex: "1h5m2s") - The time to wait for SSH to become available. Packer uses this to determine when the machine has booted so this is usually quite long. Example value: 10m. This defaults to 5m, unless ssh_handshake_attempts is set.
[…]
ssh_handshake_attempts (int) - The number of handshakes to attempt with SSH once it can connect. This defaults to 10, unless a ssh_timeout is set.
This leaves me wondering:
Are the ssh_timeout and ssh_handshake_attempts fields mutually exclusive? It kind of sounds like that, but it's not clear.
What is the value of ssh_timeout if ssh_handshake_attempts is set (and vice versa)? (if they are not mutually exclusive, of course).
This should be clarified in the documentation.
I think that the root cause for my confusion is that the default values are explained with so many conditions. If I have understood things correctly, these are the possible states for the default values:
ssh_timeout is set
ssh_handshake_attempts is set
ssh_timeout default value
ssh_handshake_attempts default value
True
True
-
-
False
True
5 min
-
True
False
-
10
False
False
5 min
10
Does this table correctly represent all possible states? If so, I see no reason for all the conditionals in explaining the fields' default values. If my table is correct, we can simply say that _"the default value for ssh_timeout is 5 min and the default value for ssh_handshake_attempts is 10"_.
Use Case(s)
The documentation should be clear on how things works.
