Helpful commands

cap prod command ROLES=role1,role2                  Run command on specified role(s)
cap prod command HOSTS=host1,host2                  Run command on specified host(s)

Configuration

Following variables are available to be changed (shown with defaults)

# env-with-secrets
set :local_path, './'
set :file_to_encrypt, 'cap-secrets-LOCAL.txt'
set :file_to_decrypt, 'cap-secrets.enc.b64'
set :encryption_key_file, 'cap-secrets-encryption-key-LOCAL.txt'
# php-fpm
set :USE_PHP_VERSION, "8.4"

env-with-secrets

This will allow you to have .env files committed to git with secrets inside (encrypted)

  • Inside .env file you need to use ="CAP_ENCRYPTED_SECRETS[something]". Examples:
    • DB_PASSWORD="CAP_ENCRYPTED_SECRETS[DB_PASSWORD]"
    • MAIL_PASSWORD="CAP_ENCRYPTED_SECRETS[MAIL_PASSWORD]"
  • After deploy, the CAP_ENCRYPTED_SECRETS[DB_PASSWORD] will be replaced to whatever secret you wrote in the secrets file for key DB_PASSWORD
    • Also, the CAP_ENCRYPTED_SECRETS will be removed; this is used for the regex to know when to replace
  • You also need 3 files - generate them by running cap {prod} env:local:encrypt_file - this will generate the files when they don't exist
    • cap-secrets-encryption-key-LOCAL.txt
      • Don't push this to git.
      • You need to manually share this with other colleagues to be able to deploy and/or encrypt/decrypt .env files.
      • This is the encryption key. You can change it to whatever you want. Default is 40 random chars.
    • cap-secrets-LOCAL.txt
      • Don't push this to git.
      • Generated by cap {prod} env:local:decrypt_file
        • Decrypts cap-secrets.enc.b64 into cap-secrets-LOCAL.txt
      • This file stores SOME_KEY="secret" on each line
        • The SOME_KEY will be used in .env files like this: SOME_VAR="CAP_ENCRYPTED_SECRETS[SOME_KEY]"
    • cap-secrets.enc.b64
      • Push this to git.
      • Generated by cap {prod} env:local:encrypt_file
        • Encrypts cap-secrets-LOCAL.txt into cap-secrets.enc.b64
  • You can also change the location and name of these files by changing the 4 variables from Configuration
    • You can also use subdirectories, but you need to create directories first.
    • Everything is related to Capfile
    • If you don't set anything, then the default is root of project (or, near the Capfile)
  • Finally, you need to have this in your deploy.rb or stages/{stage}.rb
    • before "deploy:symlink:release", "env:upload:diff"
      • I like having diff too, before upload, to see in cap {prod} deploy output the diff - if any
      • So it will be:
        • before "deploy:symlink:release", "env:upload:diff"
        • before "deploy:symlink:release", "env:upload"
    • Also, for each server line, you need to specify which .env file to use via env_file_location. Example:
      • server "web1", user: "user1", roles: %w{ app web etc }, env_file_location: '.env.prod.web1'
        • File .env.prod.web1 should exist at root of project
    • Preferably to update .gitignore file with the 2 LOCAL files
      • cap-secrets-LOCAL.txt
      • cap-secrets-encryption-key-LOCAL.txt

php-fpm

  • For each server line, you can specify which php version to use via use_php_version. Example:
    • server "web1", user: "user1", roles: %w{ app web etc }, use_php_version: 8.5
  • You can also specify (deploy.rb/{stage}.rb) a default version to use; this will be used if server's use_php_version is not set
    • set :USE_PHP_VERSION, "8.4"
  • If none is set, then default 8.2 will be used
