plugin deregister

The plugin deregister command deregisters an existing plugin from Vault's plugin catalog. If the plugin does not exist, no error is returned. The plugin's type of "auth", "database", or "secret" must be included.

Examples

Deregister a plugin:

$ vault plugin deregister auth my-custom-plugin
Success! Deregistered plugin (if it was registered): my-custom-plugin

Usage

The following flags are available in addition to the standard set of flags included on all commands.

  • -version (string: "") - Semantic version of the plugin to deregister. If unset, only an unversioned plugin may be deregistered.

plugin info

The plugin info displays information about a plugin in the catalog. The plugin's type of "auth", "database", or "secret" must be included.

deprecation_status field

As of 1.12, all builtin plugins will have an associated Deprecation Status. This status will be reflected in the deprecation_status key/value pair, seen below.

Examples

Display information about a plugin

$ vault plugin info -version=v1.0.0 auth my-custom-plugin

sha256                n/a
version               n/a

Usage

The following flags are available in addition to the standard set of flags included on all commands.

Output options

  • -field (string: "") - Print only the field with the given name. Specifying this option will take precedence over other formatting directives. The result will not have a trailing newline making it ideal for piping to other processes.

  • -format (string: "table") - Print the output in the given format. Valid formats are "table", "json", or "yaml". This can also be specified via the VAULT_FORMAT environment variable.

Command options

  • -plugin-version (string: "") - Semantic version of the plugin to read from the catalog. If unspecified, refers to the unversioned plugin registered with the same name and type, or the built-in plugin, in that order of precedence.

plugin list

The plugin list command lists all available plugins in the plugin catalog. It can be used alone or with a type such as "auth", "database", or "secret".

Deprecation status column

As of 1.12, all builtin plugins will have an associated Deprecation Status. This status will be reflected in the Deprecation Status column, seen below. All non-builtin plugins will show a Deprecation Status of "n/a".

Examples

List all available plugins in the catalog.

$ vault plugin list
Name                                 Type        Version
----                                 ----        -------
alicloud                             auth        v0.13.0+builtin
# ...

$ vault plugin list database
Name                                 Version
----                                 -------
cassandra-database-plugin            v1.13.0+builtin.vault
# ...

List detailed plugin information:

$ vault plugin list -detailed
Name        Type    Version                  Container    Deprecation Status
----        ----    -------                  ---------    ------------------
alicloud    auth    v0.12.0+builtin          false        supported
app-id      auth    v1.12.0+builtin.vault    false        pending removal
# ...

Usage

The following flags are available in addition to the standard set of flags included on all commands.

Output options

  • -format (string: "table") - Print the output in the given format. Valid formats are "table", "json", or "yaml". This can also be specified via the VAULT_FORMAT environment variable.

Command options

  • -detailed (bool: false) - Print detailed information such as version and deprecation status about each plugin.

plugin register

The plugin register command registers a new plugin in Vault's plugin catalog. The plugin's type of "auth", "database", or "secret" must be included.

Examples

Register a plugin:

$ vault plugin register \
    -sha256=d3f0a8be02f6c074cf38c9c99d4d04c9c6466249 \
    auth my-custom-plugin
Success! Registered plugin: my-custom-plugin

Register a plugin with custom args:

$ vault plugin register \
    -sha256=d3f0a8be02f6c074cf38c9c99d4d04c9c6466249 \
    -args=--with-glibc,--with-curl-bindings \
    auth my-custom-plugin

Usage

The following flags are available in addition to the standard set of flags included on all commands.

Output options

  • -format (string: "table") - Print the output in the given format. Valid formats are "table", "json", or "yaml". This can also be specified via the VAULT_FORMAT environment variable.

Command options

  • -sha256 (string: <required>) - SHA256 of the plugin binary or the OCI image provided. This is required for all plugins.

  • -args ([]string: []) - Argument to pass to the plugin when starting. This flag can be specified multiple times to specify multiple args.

  • -command (string: "") - Command to spawn the plugin. This defaults to the name of the plugin if both -oci_image and -command are unspecified.

  • -env ([]string: []) - Environment variables to set for the plugin when starting. This flag can be specified multiple times to specify multiple environment variables.

  • -oci_image (string: "") - OCI image to run. If specified, setting -command, -args, and -env will update the container's entrypoint, args, and environment variables (append-only) respectively.

  • -runtime (string: "") - Vault plugin runtime to use if -oci_image is specified.

  • -version (string: "") - Semantic version of the plugin. Used as the tag when specifying -oci_image, but any leading 'v' will automatically be trimmed.

plugin reload

The plugin reload command is used to reload mounted plugin backends. Either the plugin name (plugin) or the desired plugin backend mounts (mounts) must be provided, but not both. In the case that the plugin name is provided, all mounted paths that use that plugin backend will be reloaded.

Examples

Reload a plugin by name:

$ vault plugin reload -plugin my-custom-plugin
Success! Reloaded plugin: my-custom-plugin

Reload an auth plugin by mount:

$ vault plugin reload \
  -mounts auth/my-custom-plugin-1 \
  -mounts auth/my-custom-plugin-2
Success! Reloaded mounts: [auth/my-custom-plugin-1/ auth/my-custom-plugin-2/]

Reload a secrets plugin by mount:

$ vault plugin reload \
  -mounts my-custom-plugin-1 \
  -mounts my-custom-plugin-2
Success! Reloaded mounts: [my-custom-plugin-1/ my-custom-plugin-2/]

Usage

The following flags are available in addition to the standard set of flags included on all commands.

Command options

  • -plugin (string: "") - The name of the plugin to reload, as registered in the plugin catalog.

  • -mounts (array: []) - Array or comma-separated string mount paths of the plugin backends to reload.

  • -scope (string: "") - The scope of the reload. For local reloads, omit this flag. For reloads that span multiple Vault clusters, use global.

plugin runtime

The plugin runtime command groups subcommands for interacting with and configuring the context within which your external plugins run.

Limited type support

Support for runtime types is currently limited to `container`.

Limited OS support

Support for the 'container` runtime is currently limited to Linux.

If you register a container plugin without referencing a plugin runtime, it will use gVisor's OCI runtime runsc by default, with no resource limits. You can use plugin runtimes to configure other OCI-compliant runtimes such as runc. Vault does not come packaged with any supporting container runtimes, and you must separately install whichever you want to use.

To use a registered plugin runtime, use the -runtime option with the plugin registration command.

See containerized plugins for more details on running external plugins in containers.

Examples

Register a new plugin runtime to the catalog:

$ vault plugin runtime register -type=container -oci_runtime=runc runc
Success! Registered plugin runtime: runc

List all available plugin runtimes in the catalog:

$ vault plugin runtime list

Name    Type         OCI Runtime    Parent Cgroup    CPU Nanos    Memory Bytes
----    ----         -----------    -------------    ---------    ------------
runc    container    runc           n/a              0            0

Get information about a plugin runtime in the catalog:

$ vault plugin runtime info -type=container runc
Key              Value
---              -----
cgroup_parent    n/a
cpu_nanos        0
memory_bytes     0
name             runc
oci_runtime      runc
type             container

Usage

Usage: vault plugin runtime <subcommand> [options] [args]

  # ...
