Current Behavior
[Mutagen] fails to install it's agent on a Coder workspace were the dir property is set. For example, our Write Coder on Coder template uses:
resource "coder_agent" "dev" {
arch = "amd64"
os = "linux"
dir = local.repo_dir
env = {
OIDC_TOKEN : data.coder_workspace_owner.me.oidc_access_token,
}
startup_script_behavior = "blocking"
...
}
Mutagen works by scp'ing an agent file, then chmod'ing the file and executing it over SSH.
scp defaults to the user's home directory as the place to start any relative paths for scp. So the agent binary gets copied to ~/mutagen-agent<some UUID>. However, because we set dir in the terraform template, the default working directory for SSH is not the home directory, and so the SSH commands cannot locate the mutagen agent file.
Essentially this issue arises because Mutagen assumes scp and ssh will default to the home directory, or at least the same directory, but we break this assumption for SSH

.
Options to fix:
-
Change our SSH server to also default scp to the
dirpath by default.
a. note that successful install moves the binary and doesn't leave the file in thedirdirectory, unless there is a failure -
Patch mutagen so that it uses explicit paths

Mutagen copies its agent over and is able to file sync.
Steps to Reproduce
- Install Mutagen
- Install Coder Desktop or run
coder config-sshto get SSH working with your workspace - Push or use a template that sets the
dirproperty oncoder_agentto something other than the home directory - Create a file sync with the workspace using Mutagen
Environment
- Host OS: Windows 11
- Coder version: Coder v2.18.4+6125358
