Sorry I know I wasn't requested for a review, but I think the public key comparison could be made a bit more robust by using the library parsing functions. Something like this? var identities []ssh.PublicKey
for _, idFile := range publicKeyIdentityFiles {
keybytes, _ := os.ReadFile(idFile)
pubkey, _ := ssh.ParsePublicKey(keybytes)
identities = append(identities, pubkey)
}
for _, signer := range agentSigners {
for _, identity := range identities {
if bytes.Equal(signer.PublicKey().Marshal(), identity.Marshal()) {
// found a match
}
}
} |

There was a problem hiding this comment.
I pasted the wrong path for my public key and got this error:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x8e5c63]
goroutine 1 [running]:
github.com/uselagoon/lagoon-cli/cmd.publicKey({0xc000267de0, 0x19}, {0x0, 0x0}, {0xc00023d090, 0x1, 0x9fd275?}, 0x5?)
/home/brandon/dev/amazee-io/lagoon-cli/cmd/login.go:56 +0x8c3I immediately knew it was a spelling error, but not everyone will, can you add a "file exists" check similar to how -i has?
Otherwise, this works to use a single key from the ssh-agent as described 🎉

Updated with file check error handling, so I'll merge this now @rocketeerbkw ? |

General Checklist
This adds support for publickey identities to the config file, which allows for these to select a key if it is found in the ssh-agent
A flag can be provided too
--ssh-publickey /full/path/to/key.pubwhich will override anything defined in configurationAdditionally, a global
--verboseflag is added which can be used to print some verbose output to stderr, this could be used elsewhere in the CLI in the future too. In this PR the flag will print which key is being used or if the agent is being used, which can help users with debugging.Worth noting, once #319 is finalized, keycloak authentication will be the preferred method for authenticating the CLI to get a token, leaving these identity files to only be used for the
sshaspect the CLI provides. But they can still be used for authenticating to get a token via the SSH service still.Closing issues
