## Summary
Add `pre_clone_script` parameter to the git-clone module, allowing users
to run custom scripts before cloning a repository.
## Use Case
This solves SSH host key verification issues (e.g., "Host key
verification failed") by enabling users to configure SSH settings before
the clone operation, such as adding known hosts or setting
`StrictHostKeyChecking no`.
```tf
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "git@github.com:org/repo.git"
pre_clone_script = <<-EOT
#!/bin/bash
mkdir -p ~/.ssh
echo -e "Host github.com\n StrictHostKeyChecking no\n" > ~/.ssh/config
chmod 600 ~/.ssh/config
EOT
}
```

Git Clone
This module allows you to automatically clone a repository by URL and skip if it exists in the base directory provided.
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
}
Examples
Custom Path
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
base_dir = "~/projects/coder"
}
Git Authentication
To use with Git Authentication, add the provider by ID to your template:
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
}
data "coder_external_auth" "github" {
id = "github"
}
GitHub clone with branch name
To GitHub clone with a specific branch like feat/example
# Prompt the user for the git repo URL
data "coder_parameter" "git_repo" {
name = "git_repo"
display_name = "Git repository"
default = "https://github.com/coder/coder/tree/feat/example"
}
# Clone the repository for branch `feat/example`
module "git_clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = data.coder_parameter.git_repo.value
}
# Create a code-server instance for the cloned repository
module "code-server" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/code-server/coder"
version = "1.2.2"
agent_id = coder_agent.example.id
order = 1
folder = "/home/${local.username}/${module.git_clone[count.index].folder_name}"
}
# Create a Coder app for the website
resource "coder_app" "website" {
count = data.coder_workspace.me.start_count
agent_id = coder_agent.example.id
order = 2
slug = "website"
external = true
display_name = module.git_clone[count.index].folder_name
url = module.git_clone[count.index].web_url
icon = module.git_clone[count.index].git_provider != "" ? "/icon/${module.git_clone[count.index].git_provider}.svg" : "/icon/git.svg"
}
Configuring git-clone for a self-hosted GitHub Enterprise Server running at github.example.com
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.example.com/coder/coder/tree/feat/example"
git_providers = {
"https://github.example.com/" = {
provider = "github"
}
}
}
GitLab clone with branch name
To GitLab clone with a specific branch like feat/example
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://gitlab.com/coder/coder/-/tree/feat/example"
}
Configuring git-clone for a self-hosted GitLab running at gitlab.example.com
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://gitlab.example.com/coder/coder/-/tree/feat/example"
git_providers = {
"https://gitlab.example.com/" = {
provider = "gitlab"
}
}
}
Git clone with branch_name set
Alternatively, you can set the branch_name attribute to clone a specific branch.
For example, to clone the feat/example branch:
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
branch_name = "feat/example"
}
Git clone with different destination folder
By default, the repository will be cloned into a folder matching the repository name.
You can use the folder_name attribute to change the name of the destination folder to something else.
For example, this will clone into the ~/projects/coder/coder-dev folder:
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
folder_name = "coder-dev"
base_dir = "~/projects/coder"
}
Git shallow clone
Limit the clone history to speed-up workspace startup by setting depth.
When depth is greater than 0 the module runs git clone --depth <depth>.
If not defined, the default, 0, performs a full clone.
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
depth = 1
}
Pre-clone script
Run a custom script before cloning the repository by setting the pre_clone_script variable.
This is useful for preparing the environment or validating prerequisites before cloning.
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
pre_clone_script = <<-EOT
#!/bin/bash
echo "Preparing to clone repository..."
# Check prerequisites
command -v npm >/dev/null 2>&1 || { echo "npm is required but not installed."; exit 1; }
# Set up environment
export NODE_ENV=development
EOT
}
Post-clone script
Run a custom script after cloning the repository by setting the post_clone_script variable.
This is useful for running initialization tasks like installing dependencies or setting up the environment.
module "git-clone" {
count = data.coder_workspace.me.start_count
source = "registry.coder.com/coder/git-clone/coder"
version = "1.3.0"
agent_id = coder_agent.example.id
url = "https://github.com/coder/coder"
post_clone_script = <<-EOT
#!/bin/bash
echo "Repository cloned successfully!"
# Install dependencies
npm install
# Run any other initialization tasks
make setup
EOT
