Vault Formula

Manage Hashicorp Vault with Salt.

This formula contains several custom modules. The vault modules should be backwards-compatible with the ones currently found in Salt and might become available there at some point. For details, see #62684 and #63314.

General notes

See the full SaltStack Formulas installation and usage instructions.

If you are interested in writing or contributing to formulas, please pay attention to the Writing Formula Section.

If you want to use this formula, please pay attention to the FORMULA file and/or git tag, which contains the currently released version. This formula is versioned according to Semantic Versioning.

See Formula Versioning Section for more details.

If you need (non-default) configuration, please refer to:

• how to configure the formula with map.jinja
• the pillar.example file
• the Special notes section

Special notes

Configuration

An example pillar is provided, please see pillar.example. Note that you do not need to specify everything by pillar. Often, it's much easier and less resource-heavy to use the parameters/<grain>/<value>.yaml files for non-sensitive settings. The underlying logic is explained in map.jinja.

vault

Meta-state.

This installs Vault, manages the Vault and system swap configuration and then starts the Vault service. Also ensures the cluster is initialized if vault:init is not false.

vault.package

Installs Vault (+ necessary service unit overrides) only.

vault.package.repo

This state will install the configured vault repository. This works for apt/dnf/yum/zypper-based distributions only by default.

vault.config

Ensures the system and Vault is configured as specified.

vault.config.file

Manages the Vault configuration. Has a dependency on vault.package.

vault.config.system

Manages system settings required for Vault: disable swap. Includes vault.package.

vault.cert

Generates a TLS certificate + key for Vault. Depends on vault.package.

vault.service

Starts the vault service and enables it at boot time. Has a dependency on vault.config.

vault.initialize

Ensures a running Vault cluster has been initialized. Will output key shares and initial root token to file paths. Ensure you provide the correct GPG keys in order to encrypt the output.

vault.database

Manages database connections and their roles.

vault.leases

Manages cached leases and associated beacons.

vault.pki

vault.pki.base

Manages PKI backend URL endpoints.

vault.pki.ca

Manages intermediate CAs on PKI backend mounts.

vault.pki.roles

Manages present and absent roles on configured PKI mounts.

vault.plugins

Manages present/absent custom plugins. For present ones, pulls binaries from a URI and registers them.

vault.secrets

Manages Vault KV secrets.

vault.ssh

Manages SSH secret backend roles and, if required, CAs.

vault.ssh.ca

vault.ssh.roles

vault.clean

Meta-state.

Undoes everything performed in the vault meta-state in reverse order, i.e. stops the service, removes the configuration file and then uninstalls the package.

vault.package.clean

Removes Vault and service unit overrides. Has a dependency on vault.config.clean.

vault.package.repo.clean

This state will remove the configured vault repository. This works for apt/dnf/yum/zypper-based distributions only by default.

vault.config.clean

Removes the Vault configuration only and has a dependency on vault.service.clean.

vault.cert.clean

Removes generated Vault TLS certificate + key. Depends on vault.service.clean.

vault.service.clean

Stops the vault service and disables it at boot time.

vault.database.clean

Removes managed database connections and their roles. Requires remove_all_data_for_sure to be set to true to prevent accidental damage.

vault.leases.clean

Removes managed leases.

vault.pki.clean

Does nothing at the moment.

vault.plugins.clean

vault.secrets.clean

Removes managed secrets.

vault.ssh.clean

Removes managed SSH roles and SSH CAs. For CAs, requires remove_all_data_for_sure to be set to true to prevent accidental damage.

Commit messages

Commit message formatting is significant!

Please see How to contribute for more details.

pre-commit

pre-commit is configured for this formula, which you may optionally use to ease the steps involved in submitting your changes. First install the pre-commit package manager using the appropriate method, then run bin/install-hooks and now pre-commit will run automatically on each git commit.

$ bin/install-hooks
pre-commit installed at .git/hooks/pre-commit
pre-commit installed at .git/hooks/commit-msg

State documentation

There is a script that semi-autodocuments available states: bin/slsdoc.

If a .sls file begins with a Jinja comment, it will dump that into the docs. It can be configured differently depending on the formula. See the script source code for details currently.

This means if you feel a state should be documented, make sure to write a comment explaining it.
