README.md for PowerBuf CLI

PowerBuf CLI

The pbuf is a Command Line Interface (CLI) tool for PowerBuf, allowing you to easily manage, and vendor modules.

We recommend using pbuf with the PowerBuf Registry.

Installation

Quick Install (Linux/macOS)

Install the latest version with a single command:

curl -fsSL https://raw.githubusercontent.com/pbufio/pbuf-cli/main/install.sh | sh

Or using wget:

wget -qO- https://raw.githubusercontent.com/pbufio/pbuf-cli/main/install.sh | sh

The script will:

Auto-detect your OS and architecture
Download the latest release
Install to /usr/local/bin (may require sudo)

To install to a custom directory:

INSTALL_DIR=$HOME/.local/bin curl -fsSL https://raw.githubusercontent.com/pbufio/pbuf-cli/main/install.sh | sh

Windows

Option 1: Manual Download

Download the latest Windows release from: https://github.com/pbufio/pbuf-cli/releases
Extract the pbuf.exe binary from the zip archive
Add the binary to your PATH:
- Right-click "This PC" → Properties → Advanced system settings → Environment Variables
- Under "System variables", find and edit "Path"
- Add the directory containing pbuf.exe
Verify installation by opening a new terminal and running:
```

Option 2: PowerShell Script

# Download and extract (run as Administrator if installing to Program Files)
$version = (Invoke-RestMethod "https://api.github.com/repos/pbufio/pbuf-cli/releases/latest").tag_name
$arch = if ([Environment]::Is64BitOperatingSystem) { "amd64" } else { "386" }
$url = "https://github.com/pbufio/pbuf-cli/releases/download/$version/pbuf_${version}_windows_${arch}.zip"
$output = "$env:TEMP\pbuf.zip"

Invoke-WebRequest -Uri $url -OutFile $output
Expand-Archive -Path $output -DestinationPath "$env:TEMP\pbuf" -Force
Move-Item -Path "$env:TEMP\pbuf\pbuf.exe" -Destination "C:\Windows\System32\" -Force
Remove-Item -Path $output, "$env:TEMP\pbuf" -Recurse -Force

Write-Host "pbuf installed successfully!"
pbuf --help

From Source

If you have Go installed, you can build from source:

go install github.com/pbufio/pbuf-cli@latest

Or for a specific version:

go install github.com/pbufio/pbuf-cli@<tag>

Manual Binary Download

Download pre-built binaries for all platforms from the releases page: https://github.com/pbufio/pbuf-cli/releases

Self-Hosted Quickstart

Get started with a self-hosted PowerBuf Registry in under 5 minutes:

1. Start the Registry

# Using Docker
docker run -d -p 8080:8080 pbufio/pbuf-registry:latest

# Or using Docker Compose
# See https://github.com/pbufio/pbuf-registry for examples

2. Initialize Your Project

# Initialize with your registry URL
pbuf init my-module http://localhost:8080

# Or for HTTPS with valid cert
pbuf init my-module https://registry.mycompany.com

3. Authenticate (if required)

# Set your authentication token
pbuf auth your-token-here

4. Create a Proto File

mkdir -p api/v1
cat > api/v1/service.proto << 'EOF'
syntax = "proto3";
package mycompany.mymodule.v1;

message HelloRequest {
  string name = 1;
}

message HelloResponse {
  string message = 1;
}
EOF

Update pbuf.yaml to export your proto files:

export:
  paths:
    - api

5. Push Your Module

pbuf modules push v0.0.1

6. Vendor in Another Project

# In another project
pbuf init consumer-service http://localhost:8080
# Edit pbuf.yaml to add your module as dependency
pbuf vendor

Your protos are now vendored in third_party/ and ready to use!

Usage

General Structure

The general structure of commands is:

pbuf [command] [arguments...]

Available Commands

Init

The init command allows you to initialize a new pbuf.yaml file.

Interactively:

pbuf init

Non-interactively:

pbuf init [module_name] [registry_url]

Replace [module_name] with the name of the module you want to register. Replace [registry_url] with the URL of the PowerBuf Registry (by default it uses pbuf.cloud).

Auth (if applicable)

The auth command allows you to authenticate with the registry. It saves the token in the .netrc file.

pbuf auth [token]

Vendor

The vendor command allows you to vendor modules from provided configuration.

pbuf vendor

By default, this command reads the configuration from pbuf.yaml. The configuration provides details like the repository, branch or tag, path, and output directory for each module.

Register Module

The register command allows you to register a module to the registry.

pbuf modules register

You can register a module by providing the following details in pbuf.yaml:

version: v1
name: [module_name]
...

Replace [module_name] with the name of the module you want to register.

Get Module

The get command allows you to get the information about a module from the registry.

pbuf modules get [module_name]

Response example:

{
  "id": "b9f9898a-8510-4017-9618-5244176eb1b8",
  "name": "pbufio/pbuf-registry",
  "tags": [
    "v0.0.0",
    "v0.1.0"
  ]
}

If module_name is not provided, the name from pbuf.yaml is used.

List Modules

The list command allows you to list all modules from the registry.

pbuf modules list

Response example:

[
  {
    "id": "b9f9898a-8510-4017-9618-5244176eb1b8",
    "name": "pbufio/pbuf-registry"
  },
  {
    "id": "b9f9898a-8510-4017-9618-5244176eb1b8",
    "name": "pbufio/pbuf-cli"
  }
]

Push Module

The push command allows you to push .proto files to the registry with a specific tag.

pbuf modules push [tag] [--draft]

Replace [tag] with the tag you want to push. Use the --draft flag to push a draft tag.

Draft tags are temporary tags that are automatically deleted in a week.

Update Modules Tags

The update command allows you to update the modules' tags to the latest in the registry. The command saves the latest tags in the pbuf.yaml file for each module.

pbuf modules update

Delete Tag

The delete command allows you to delete a tag from the registry.

pbuf modules delete-tag [tag]

The command deletes all the proto files associated with the tag.

Delete Module

The delete command allows you to delete a module from the registry.

pbuf modules delete [module_name]

The command deletes all the tags and proto files associated with the module.

Configuration (`pbuf.yaml`)

A typical pbuf.yaml file contains the following:

version: v1
name: [module_name]
registry:
  addr: [registry_url]
  insecure: false # set to true only for local dev with HTTP; use false (default) for HTTPS in production
export:
  paths:
    - [proto_files_path]
modules:
  # use the registry to vendor .proto files
  - name: [dependency_module_name]
    path: [path_in_registry]
    tag: [dependency_module_tag]
    out: [output_folder_on_local]
    gen_out: [gen_output_folder_on_local] # optional, if provided then patchers will be applied
  # use a git repository to vendor .proto files
  - repository: [repository_url]
    path: [path_in_repository]
    branch: [branch_name]
    tag: [tag_name]
    out: [output_folder_on_local]
    gen_out: [gen_output_folder_on_local] # optional, if provided then patchers will be applied

Replace main placeholders with appropriate values:

[module_name]: The module name you want to register.
[registry_url]: The URL of the pbuf-registry.
[proto_files_path]: One or several paths that contain .proto files.

Replace placeholders in the registry modules with appropriate values:

[dependency_module_name]: The module name you want to vendor.
[path_in_registry]: Path to the folder or file in the registry you want to vendor.
[tag_name]: Specific tag to vendor.
[output_folder_on_local]: Folder where the vendor content should be placed on your local machine.
[gen_output_folder_on_local]: Folder where the generated content should be placed on your local machine. Used to patch go_package option

Replace placeholders in modules placed in git with appropriate values:

[repository_url]: The URL of the Git repository.
[path_in_repository]: Path to the folder or file in the repository you want to vendor.
[branch_name]: Specific branch name to clone (optional if tag is provided).
[tag_name]: Specific tag to clone (optional if branch is provided).
[output_folder_on_local]: Folder where the vendor content should be placed on your local machine.
[gen_output_folder_on_local]: Folder where the generated content should be placed on your local machine. Used to patch go_package option

Examples

Push Module

version: v1
name: pbufio/pbuf-registry
registry:
  addr: pbuf.cloud
  insecure: false # pbuf.cloud uses HTTPS; set to true only for local HTTP registries
# all `.proto` files from `api` and `entities` folders
# will be exported as the module proto files
export:
  paths:
    - api
    - entities
modules: []

Vendor Modules

version: v1
name: pbuf-cli
registry:
   addr: pbuf.cloud
   insecure: false # use HTTPS for production registries
modules:
  # will copy api/v1/*.proto file to third_party/api/v1/*.proto
  - name: pbufio/pbuf-registry
    tag: v0.0.1
    out: third_party
  # will copy api/v1/*.proto file to third_party/api/v1/*.proto
  # and add or change `go_package` option to `<go_mod_name>/gen/pbuf-registry/api/v1`
  - name: pbufio/pbuf-registry
    tag: v0.0.1
    out: third_party
    gen_out: gen
  # will copy examples/addressbook.proto file to proto/addressbook.proto
  - repository: https://github.com/protocolbuffers/protobuf
    path: examples/addressbook.proto
    branch: main
    out: proto
  # will copy examples folder to examples folder
  - repository: https://github.com/protocolbuffers/protobuf
    path: examples
    tag: v24.4

Security & Authentication

.netrc Authentication

pbuf uses the .netrc file for authentication with registries and private Git repositories. Ensure your .netrc file is properly configured in your home directory (~/.netrc).

For PowerBuf Registry with static token authentication:

machine <registry_host>
token <token>

Example:

machine pbuf.cloud
token 1234567890

For private Git repositories:

machine github.com
login <username>
password <personal_access_token>

CI/CD Integration

GitHub Actions:

- name: Setup .netrc
  run: |
    echo "machine pbuf.cloud" > ~/.netrc
    echo "token ${{ secrets.PBUF_TOKEN }}" >> ~/.netrc
    chmod 600 ~/.netrc

- name: Vendor protos
  run: pbuf vendor

GitLab CI:

before_script:
  - echo "machine pbuf.cloud" > ~/.netrc
  - echo "token ${PBUF_TOKEN}" >> ~/.netrc
  - chmod 600 ~/.netrc

vendor:
  script:
    - pbuf vendor

Security Best Practices

Never commit .netrc files to version control
Use environment variables or secrets management in CI/CD
Set proper file permissions: chmod 600 ~/.netrc
For production registries, always use HTTPS (insecure: false)
Rotate tokens regularly
