### Syntax

`ern platform config set <key> <value>`

**Arguments**

`<key>`

* The key of the configuration element to set

`<value>`

* If specified, will set the config value associated to this key.

**Configurable properties**

* `codePushAccessKey` \[string] Code push access key associated with your account
* `codePushCustomHeaders` \[string] CodePush custom extra http headers.
* `codePushCustomServerUrl` \[string] CodePush custom server url, in case you are not using the Microsoft CodePush server.
* `codePushProxy` \[string] CodePush proxy server url.
* `ignore-required-ern-version` \[boolean] Indicates whether any Cauldron ern version requirement should be ignored. This is mostly used for Electrode Native development and should not be set to true otherwise. **default** : false
* `logLevel` \[trace|debug|info|error|fatal] Set the log level to use for all commands. **default** : info
* `max-package-cache-size` \[number] The maximum disk space to use for the package cache, in Bytes. Only apply if the package cache is enabled (`package-cache-enabled` configuration key set to `true`). **default** : 2GB
* `package-cache-enabled` \[boolean] Indicates whether the package cache should be enabled. Enabling the package cache will lead to faster Containers generation, given that all packages versions used for a Container generation, will be retrieved from the cache if available rather than being downloaded upon every generation. **default** : true
* `podVersion` \[string] Version of CocoaPods (pod command) to use for iOS container generation. **The version must be available (installed) locally** **default** : default CocoaPods version for environment
* `retain-tmp-dir` \[boolean] If set to `true`, the temporary directories created during some commands execution, won't be destroyed after the command execution. **default** : false
* `showBanner` \[boolean] Show the Electrode Native ASCII banner for all commands. **default** : true
* `tmp-dir` \[string] Temporary directory to use during commands execution. **default** : system default
* `bundleStoreProxy` \[string] HTTP/HTTPS proxy to use to connect to the bundle store server. Should be the full url to the proxy, including the port. For example `http://10.0.0.0:9089`. **default** : no proxy
* `sourceMapStoreProxy` \[string] HTTP/HTTPS proxy to use to connect to the source map store server. Should be the full url to the proxy, including the port. For example `http://10.0.0.0:9089`. **default** : no proxy
* `binaryStoreProxy` \[string] HTTP/HTTPS proxy to use to connect to the binary store server. Should be the full url to the proxy, including the port. For example `http://10.0.0.0:9089`. **default** : no proxy
* `manifest` \[object] Master and/or override manifest paths to be used locally. **If this object is defined in the local configuration, it will take precedence over any cauldron manifest configuration**

For example :

```javascript
{
  "manifest": {
    "master": {
      "url": "/local/path/to/master/manifest"
    },
    "override": {
      "type": "partial",
      "url": "/local/path/to/override/manifest"
    }
  }
}
```

### Remarks

* In case a value already exists in the configuration for a given key, this command will not fail and will overwrite the existing value.

## Placeholders

Electrode Native supports the following placeholders and will replace them accordingly when loading the configuration :

* `${env.ENV_VAR_KEY}` Will be replaced with the value of `ENV_VAR_KEY` environment variable.
* `${ERNRC}` Will be replaced with the path to the directory containing the resolved `.ernrc` configuration.
* `${PWD}` Will be replaced with current process working directory.
