Bug Report

I can't do functional test as it's just normal setup for Drupal 8 recipe. This works in our other computers but fails just in 1.

Tell us about your setup

This problem occurs on both Lando v3.0.0-rc.1 and v3.0.0-beta.47.
OS is MacOS High Sierra version 10.13.4.

Tell us about the command you were running

The project is running composer install inside the app but fails when GIT submodules need to get downloaded. The reason is that it can't find the ssh keys. When I checked the contents of /etc/ssh/ssh_config inside the container on my computer and on the problematic computer then I saw it was missing IdentityFile locations. On problematic container it's:

Host *
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
  LogLevel=ERROR

On the working environment it's:

Host *
  StrictHostKeyChecking no
  UserKnownHostsFile=/dev/null
  LogLevel=ERROR
  IdentityFile /user/.ssh/id_rsa

When we manually added the line then git submodules where pulled successfully.

One other way we tested this was trying

ssh -T git@github.com

on host and in container. It failed inside the docker container but connected successfully in host.

The problem happened on v3.0.0-beta.47. We downloaded latest Lando and used the uninstalled script it had (also uninstalled Docker). Then we deleted the ~/.lando folder. After that installed the latest v3.0.0-rc.1, did 'lando start' and still the same problem. Currently it's fixed with the manual entry to /etc/ssh/ssh_config.

Would like to know how Lando populates the etc/ssh/ssh_config inside the container. What could be the reason it's failing?

@hkirsman id try this out on the next release (rc.4) and reopen if its still a no go
