+ </h3>
+
+ <p>
+ Use configuration providers to load configuration data from external
sources. This might include sensitive information, such as passwords, API keys,
or other credentials.
+ </p>
+
+ <p>You have the following options:</p>
+ <ul>
+ <li>
+ Use a custom provider by creating a class implementing the
+ <a
href="/{{version}}/javadoc/org/apache/kafka/common/config/provider/ConfigProvider.html"><code>ConfigProvider</code></a>
interface and packaging it into a JAR file.
+ </li>
+ <li>Use a built-in provider:</li>
+ <ul>
+ <li><a
href="/{{version}}/javadoc/org/apache/kafka/common/config/provider/DirectoryConfigProvider.html"><code>DirectoryConfigProvider</code></a></li>
+ <li><a
href="/{{version}}/javadoc/org/apache/kafka/common/config/provider/EnvVarConfigProvider.html"><code>EnvVarConfigProvider</code></a></li>
+ <li><a
href="/{{version}}/javadoc/org/apache/kafka/common/config/provider/FileConfigProvider.html"><code>FileConfigProvider</code></a></li>
+ </ul>
+ </ul>
+
+ <p>
+ To use a configuration provider, specify it in your configuration using
the <code>config.providers</code> property.
+ </p>
+
+ <h4 class="anchor-heading">
+ <a id="using_config_providers" class="anchor-link"></a>
+ <a href="#using_config_providers">Using Configuration Providers</a>
+ </h4>
+ <p>Configuration providers allow you to pass parameters and retrieve
configuration data from various sources.</p>
+ <p>To specify configuration providers, you use a comma-separated list of
aliases and the fully-qualified class names that implement the configuration
providers:</p>
+ <pre><code>config.providers=provider1,provider2
+config.providers.provider1.class=com.example.Provider1
+config.providers.provider2.class=com.example.Provider2</code></pre>
+ <p>Each provider can have its own set of parameters, which are passed in a
specific format:</p>
+
<pre><code>config.providers.<provider_alias>.param.<name>=<value></code></pre>
+ <p>The <code>ConfigProvider</code> interface serves as a base for all
configuration providers.
+ Custom implementations of this interface can be created to retrieve
configuration data from various sources.
+ You can package the implementation as a JAR file, add the JAR to your
classpath, and reference the provider's class in your configuration.</p>
+ <p><b>Example custom provider configuration</b></p>
+ <pre><code>config.providers=customProvider
+config.providers.customProvider.class=com.example.customProvider
+config.providers.customProvider.param.param1=value1
+config.providers.customProvider.param.param2=value2</code></pre>
+
+ <h4 class="anchor-heading">
+ <a id="directory_config_provider" class="anchor-link"></a>
+ <a href="#directory_config_provider">DirectoryConfigProvider</a>
+ </h4>
+ <p>The <code>DirectoryConfigProvider</code> retrieves configuration data
from files stored in a specified directory.</p>
+ <p>Each file represents a key, and its content is the value. This provider
is useful for loading multiple configuration files and for organizing
configuration data into separate files.</p>
+ <p>To restrict the files that the <code>DirectoryConfigProvider</code> can
access, use the <code>allowed.paths</code> parameter.
+ This parameter accepts a comma-separated list of paths that the provider
is allowed to access. If not set, all paths are allowed.</p>
+ <p><b>Example <code>DirectoryConfigProvider</code> configuration</b></p>
+<pre><code>config.providers=dirProvider
+config.providers.dirProvider.class=org.apache.kafka.common.config.provider.DirectoryConfigProvider
+config.providers.dirProvider.param.allowed.paths=/path/to/dir1,/path/to/dir2</code></pre>
+ <p>
+ To reference a value supplied by the <code>DirectoryConfigProvider</code>,
use the correct placeholder syntax:
+ </p>
+<pre><code>${dirProvider:<path_to_file>:<file_name>}</code></pre>
+
+ <h4 class="anchor-heading">
+ <a id="env_var_config_provider" class="anchor-link"></a>
+ <a href="#env_var_config_provider">EnvVarConfigProvider</a>
+ </h4>
+ <p>The <code>EnvVarConfigProvider</code> retrieves configuration data from
environment variables.</p>
+ <p>No specific parameters are required, as it reads directly from the
specified environment variables.</p>
+ <p>This provider is useful for configuring applications running in
containers, for example, to load certificates or JAAS configuration from
environment variables mapped from secrets.</p>
+ <p>To restrict which environment variables the
<code>EnvVarConfigProvider</code> can access, use the
<code>allowlist.pattern</code> parameter. This parameter accepts a regular
expression that environment variable names must match to be used by the
provider.</p>
+ <p><b>Example <code>EnvVarConfigProvider</code> configuration</b></p>
+<pre><code>config.providers=envVarProvider
+config.providers.envVarProvider.class=org.apache.kafka.common.config.provider.EnvVarConfigProvider
+config.providers.envVarProvider.param.allowlist.pattern=^MY_ENVAR1_.*</code></pre>
+ <p>
+ To reference a value supplied by the <code>EnvVarConfigProvider</code>,
use the correct placeholder syntax:
+ </p>
+<pre><code>${envVarProvider:<enVar_name>}</code></pre>
+
+ <h4 class="anchor-heading">
+ <a id="file_config_provider" class="anchor-link"></a>
+ <a href="#file_config_provider">FileConfigProvider</a>
+ </h4>
+ <p>The <code>FileConfigProvider</code> retrieves configuration data from a
single properties file.</p>
+ <p>This provider is useful for loading configuration data from mounted
files.</p>
+ <p>To restrict the file paths that the <code>FileConfigProvider</code> can
access, use the <code>allowed.paths</code> parameter. This parameter accepts a
comma-separated list of paths that the provider is allowed to access. If not
set, all paths are allowed.</p>
+ <p><b>Example <code>FileConfigProvider</code> configuration</b></p>
+<pre><code>config.providers=fileProvider
+config.providers.fileProvider.class=org.apache.kafka.common.config.provider.FileConfigProvider
+config.providers.fileProvider.param.allowed.paths=/path/to/config1,/path/to/config2</code></pre>
+ <p>
+ To reference a value supplied by the <code>FileConfigProvider</code>, use
the correct placeholder syntax:
+ </p>
+<pre><code>${fileProvider:<path_and_filename>:<property>}</code></pre>
+
+ <h4 class="anchor-heading">
+ <a id="ref_config_provider" class="anchor-link"></a>
+ <a href="#ref_config_provider">Example: Referencing files</a>
+ </h4>
+ <p>
+ Here’s an example that uses a file configuration provider with Kafka
Connect to provide authentication credentials to a database for a connector.
+ </p>
+ <p>
+ First, create a <code>connector-credentials.properties</code>
configuration file with the following credentials:
+ </p>
+ <pre><code>dbUsername=my-username
+dbPassword=my-password</code></pre>
+ <p>
+ Specify a <code>FileConfigProvider</code> in the Kafka Connect
configuration:
+ </p>
+ <p><b>Example Kafka Connect configuration with a
<code>FileConfigProvider</code></b></p>
+ <pre><code>config.providers=fileProvider
+config.providers.fileProvider.class=org.apache.kafka.common.config.provider.FileConfigProvider</code></pre>
+ <p>Next, reference the properties from the file in the connector
configuration.</p>
+ <p><b>Example connector configuration referencing file properties</b></p>
+
<pre><code>database.user=${fileProvider:/path/to/connector-credentials.properties:dbUsername}
+database.password=${fileProvider:/path/to/connector-credentials.properties:dbPassword}</code></pre>
+ <p>At runtime, the configuration provider reads and extracts the values from
the properties file.</p>
