How to Install Pomerium on OpenBSD

Pomerium is an open-source tool that provides a secure access proxy to your internal applications. Here are the steps to install Pomerium on OpenBSD:

  1. Install Go on your OpenBSD machine:
$ pkg_add go
  1. Set the PATH variable to include the Go binary directory:
$ echo "export PATH=$PATH:/usr/local/go/bin" >> .profile
$ source .profile
  1. Install git and clone the Pomerium repository:
$ pkg_add git
$ git clone https://github.com/pomerium/pomerium.git
  1. Build the Pomerium binary:
$ cd pomerium
$ go build
  1. Generate a self-signed certificate:
$ openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout pomerium.key -out pomerium.crt
  1. Create a configuration file for Pomerium:
$ touch config.yaml

Here's an example configuration file:

---
authenticate_service_url: https://auth.example.com
client_id: pomerium
client_secret: secret
cookie_secret: some-secret-key
default_upstream_timeout: 30s
idp:
  provider: google
  client_id: google-client-id
  client_secret: google-client-secret
  service_account: path/to/gcp-service-account.json
  service_account_project_id: google-project-id
  service_account_subject: [email protected]
  scopes:
  - email
  - profile
listen_address: :8443
log_level: debug
routes:
  - from: oauth2
    to: https://oauth2.googleapis.com
    allow_websockets: true
  - from: /
    to: http://app-server:8080
    allow_websockets: true
tls_cert_file: /path/to/pomerium.crt
tls_key_file: /path/to/pomerium.key
  1. Start Pomerium:
$ ./pomerium --config config.yaml

That's it! You should now have a Pomerium access proxy running on your OpenBSD machine.
