Customize Code Manager configuration in Hiera

Set parameters in Hiera to customize your Code Manager configuration.

To customize your configuration:
  1. In your control repo, open the data/common.yaml file.
  2. Add parameters to the puppet_enterprise::master::code_manager class. Use the following format:
    puppet_enterprise::master::code_manager::<PARAMETER>: <SETTING>
    For example, these parameters increase the size of the default worker pool and reduce the maximum time allowed to deploy a single environment:
    puppet_enterprise::master::code_manager::deploy_pool_size: 4
    puppet_enterprise::master::code_manager::timeouts_deploy: 300

    Some parameters are described in detail below, along with a list of all Code Manager parameters.

  3. Run Puppet on the primary server. The Puppet run updates the Code Manager configuration file.
    Important: Do not manually edit the Code Manager configuration file. Puppet automatically manages this file, and it overwrites or discards any manual changes you make.

Configuring post-environment hooks

Post-environment hooks can trigger custom actions after deploying an environment.

To configure list of hooks to run after Code Manager deploys code to an environment, specify the post_environment_hook parameter in Hiera. This parameter accepts an array of hashes with the url and use-client-ssl keys.

The url key specifies an HTTPS URL to send a POST request to. The request includes a JSON-formatted body containing information about the environment deployment, such as:
{
     "deploy-signature":"482f8d3adc76b5197306c5d4c8aa32aa8315694b",
     "file-sync":{
       "environment-commit":"6939889b679fdb1449545c44f26aa06174d25c21",
       "code-commit":"ce5f7158615759151f77391c7b2b8b497aaebce1"},
     "environment":"production",
     "id":3,
     "status":"complete"
   }

The use-client-ssl key is a Boolean indicating whether the client's SSL configuration is used for HTTPS connections. Set this to true if the url destination is a server that uses the Puppet CA. Otherwise, set this to false. If unspecified, the default is false.

For example, the following settings instruct Code Manager to update classes in the console after deploying code to environments:
puppet_enterprise::master::code_manager::post_environment_hooks: 
  - url: 'https://console.example.com:4433/classifier-api/v1/update-classes' 
    use-client-ssl: true 
If you wanted to configure multiple post-environment hooks, you would add more hashes to the array.

Configuring garbage collection

By default, Code Manager retains environment deployments in memory for one hour. You can adjust this by configuring garbage collection.

To configure the frequency of Code Manager garbage collection, specify the deploy_ttl parameter in Hiera. This parameter accepts a string that includes one of the following suffixes:
  • d: Days
  • h: Hours
  • m: Minutes
  • s: Seconds
  • ms: Milliseconds

For example, deploy_ttl: '30d' configures Code Manager to keep deployments in memory for 30 days. Similarly, deploy_ttl: '48h' retains deployments in memory for 48 hours.

The default setting is 1h (one hour).

Important: If the value of deploy-ttl is less than the combined values of timeouts_fetch, timeouts_sync, and timeouts_deploy, then all completed deployments are retained indefinitely. This could significantly slow Code Manager's performance over time. Refer to Code Manager parameters for information about the timeouts_* parameters.

Configuring Forge settings

To configure how Code Manager downloads modules from the Forge, specify the forge_settings parameter in Hiera.

This parameter specifies where Forge modules are installed from, and it sets a proxy for all Forge interactions. The forge_settings parameter accepts a hash that can use the following keys:
  • baseurl: Indicate where Forge modules are installed from. The default is https://forgeapi.puppetlabs.com.
  • authorization_token: Specify the token for authenticating to a custom Forge server.
  • proxy: Set the proxy for all Forge interactions.
For example, this configuration specifies a custom Forge server that doesn't require authentication:
puppet_enterprise::master::code_manager::forge_settings: 
  baseurl: 'https://private-forge.example'
If your custom Forge server requires authentication, you must specify both baseurl and authorization_token. You must format authorization_token as a string prepended with Bearer, particularly if you use Artifactory as your Forge server. For example:
puppet_enterprise::master::code_manager::forge_settings: 
  baseurl: 'https://private-forge.example'
  authorization_token: 'Bearer <TOKEN>'
The proxy parameter sets a proxy for all Forge interactions. This setting overrides the global proxy setting but only for Forge operations (refer to the global proxy setting for more information). You can set an unauthenticated proxy or an authenticated proxy with either Basic or Digest authentication. For example:
puppet_enterprise::master::code_manager::forge_settings: 
  proxy: 'http://proxy.example.com:3128'
Tip: If you set a global proxy, but you don't want Forge operations to use a proxy, under the forge_settings parameter, set proxy to an empty string.

Configuring Git settings

To configure Code Manager to use a private key, a proxy, or multiple Git source repositories, specify the git_settings parameter in Hiera.

Restriction: You can't use the git_settings parameter with the default Code Manager r10k_private_key settings. To avoid errors, remove the r10k_private_key parameter from the puppet_enterprise::profile::master class.

The git_settings parameter accepts a hash that can use the private-key, proxy, and repositories keys.

private-key

The private-key setting is required, and, if it is not specified, it gets a default value from the puppet_enterprise::profile::master class.

Use private-key to specify the path to the file containing the default private key that you want Code Manager to use to access control repos, for example:
/etc/puppetlabs/puppetserver/ssh/id-control_repo.ed25519
Important: The pe-puppet user must have read permissions for the private key file, and the SSH key can't require a password.

proxy

The proxy key sets a proxy specifically for Git operations that use an HTTP(S) transport. This setting overrides the global proxy setting but only for Git operations (For more information, refer to the global proxy setting). You can set an unauthenticated proxy or an authenticated proxy with either Basic or Digest authentication. For example:
proxy: 'http://proxy.example.com:3128'
Tip:

To set a proxy for only one specific Git repository (or when you have multiple control repos), set proxy within the repositories key.

If you set a global proxy, but you don't want Git operations to use a proxy, under the git_settings parameter, set proxy to an empty string.

repositories

The repositories key specifies a list of repositories and their respective private keys or proxies. Use repositories if:
  • You need to configure different proxy settings for specific repos, instead of all Git operations.
  • You have multiple control repos.
    Important: If you have multiple control repos, the sources setting and the repositories setting must match.

The repositories setting accepts a hash that uses the remote, private-key, and proxy keys.

The remote key specifies the repository to which the subsequent private-key or proxy setting applies. The private-key and proxy settings have the same requirements and functions as described above, except that, when inside repositories, these settings only apply to a single repository.

For example, this repositories hash specifies unique private keys for two repos and a unique proxy for a third repo:
repositories: 
  - remote: "jfkennedy@gitserver.puppetlabs.net:repositories/repo_one.git"
  private-key: "/test_keys/jfkennedy"
  - remote: "whtaft@gitserver.puppetlabs.net:repositories/repo_two.git"
  private-key: "/test_keys/whtaft"
  - remote: "https://git.example.com/git_repos/environments.git"
  proxy: "https://proxy.example.com:3128"
Tip: If you set a global proxy or a git_settings proxy, but you don't want a specific repo to use a proxy, in the repositories hash, set that specific repo's proxy to an empty string.

Configuring proxies

If you need Code Manager to use a proxy connection, use the proxy parameter. You can set a global proxy for all HTTP(S) operations, proxies for Git or Forge operations, or proxies for individual Git repositories.

Where you specify the proxy parameter depends on how you want to apply the setting:
  • To set a proxy for all Code Manager operations occurring over an HTTP(S) transport, set the global proxy setting.
  • To set proxies only for Git operations or individual Git repos, set the appropriate proxy key under the git_settings parameter.
  • To set a proxy only for Forge operations, set the proxy key under the forge_settings parameter.
You can set an unauthenticated proxy or an authenticated proxy with either Basic or Digest authentication. For example, this setting is for an unauthenticated proxy:
proxy: 'http://proxy.example.com:3128'
Whereas this setting is for a password-authenticated proxy:
proxy: 'http://user:password@proxy.example.com:3128'

Override proxy settings

You can override the global proxy setting if you want to:
  • Set a different proxy setting for Git or Forge operations.
  • Specify a different proxy setting for an individual Git repo.
  • Specify a mix of proxy and non-proxy connections.
To override the global proxy setting for all Git or Forge operations, you need to set the proxy key under the git_settings or forge_settings parameters.

To set a proxy for an individual Git repository (or if you have multiple control repos), set the proxy key in the repositories hash under the git_settings parameter.

If you have set a global, Git, or Forge proxy, but you don't want a certain setting to use any proxy, set the proxy parameter to an empty string. For example, if you set a global proxy, but you don't want Forge operations to use a proxy, you would specify an empty string under the forge_settings parameter, such as:
puppet_enterprise::master::code_manager::forge_settings: 
  proxy: ''

Configuring sources

If you are managing multiple control repos with Code Manager, you must use the sources parameter to specify a map of your source repositories.

The sources parameter is necessary when Code Manager is managing multiple control repos. For example, your Puppet environments are in one control repo and your Hiera data is in a separate control repo.

Important:

The sources setting and the repositories setting (under git_settings) must match.

If sources is set, you can't use Code Manager's global remote parameter.

The sources parameter consists of a list of source names along with a hash containing the remote and prefix key for each source. For example:
myorg: 
  remote: "git://git-server.site/myorg/main-modules"
  prefix: true
mysource: 
  remote: "git://git-server.site/mysource/main-modules"
  prefix: "testing"

The remote parameter specifies the location from which to fetch the source repo. Code Manager must be able to fetch the remote without any interactive input. This means fetching the source can't require inputting a user name or password. You must supply a valid URL, as a string, that Code Manager can use to clone the repo, such as: "git://git-server.site/myorg/main-modules"

The prefix parameter specifies a string to use as a prefix for the names of environments derived from the specified source. Set this to a specific string if you want to use a specific prefix, such as "testing". Set this to true to use the source's name as the prefix. The prefix parameter prevents collisions (and confusion) when multiple sources with identical branch names are deployed into the same directory.

For example, the following settings might cause errors or confusion because there would be two main-modules environments deployed to the same base directory:
myorg: 
     remote: "git://git-server.site/myorg/main-modules"
     prefix: true
   mysource: 
     remote: "git://git-server.site/mysource/main-modules"
     prefix: true
However, by changing one prefix to "testing", the two environments become more distinct, since the directory would now have a main-modules environment and a testing-main-modules environment:
myorg: 
     remote: "git://git-server.site/myorg/main-modules"
     prefix: true
   mysource: 
     remote: "git://git-server.site/mysource/main-modules"
     prefix: "testing"

Code Manager parameters

Parameter Description Type Default value
remote A valid SSH URL specifying the location of your Git control repository, if you have only one control repo.

If you have multiple Git repos, specify sources instead of remote. If you specify both sources and remote, then sources overrides remote.
