How to set StrictHostKeyChecking "no"?

[garak]

Using version 7-beta3, with this config:

host('foo')
    ->setHostname('myIpAddress')
    ->set('deploy_path', '~/projects/{{application}}')
;

I'm getting problem about "authenticity of host can't be established", with question "you sure you want to continue connecting (yes/no)?"
In a context of CI, where I can't reply to such question, how can I set StrictHostKeyChecking=no?

I tried with this:

host('foo')
    ->setHostname('myIpAddress')
    ->set('deploy_path', '~/projects/{{application}}')
    ->setSshArguments(['StrictHostKeyChecking' => 'no'])
;

but it doesn't work, I'm getting error ssh: Could not resolve hostname no: No address associated with hostname

In Deployer v7 ssh options were refactored. You can do it like this:

host('deployer.org')
    ->setSshArguments(['-o StrictHostKeyChecking=no']);

There is always -vvv option to debug what Deployer is doing in the background.

PS Docs updates will be soon, with a better explanation of why this refactoring was introduced.

I'm still in trouble...

host('foo')
    ->setHostname('myIpAddress')
    ->set('deploy_path', '~/projects/{{application}}')
    ->set('user', 'myuser')
    ->setSshArguments(['-o StrictHostKeyChecking=no -o BatchMode=yes'])
;

but I see (using -vvv) the following command is issued during connect:

ssh -N -o StrictHostKeyChecking=no -o BatchMode=yes -A -o ControlMaster=auto -o ControlPersist=60 -o ControlPath=/dev/shm/%C myIpAddress

resulting in an access denied error, because the user is not specified

Replace user with remote_user

Instead of disabling the host key check you can add the host key before executing deployer by running: ssh-keyscan myIpAddress >> ~/.ssh/known_hosts.
