create-container
- Create a new Container project locally.
ern create-container
Options
--baseComposite <compositePath>
- Git or File System path, to the custom Composite repository (refer to the custom Composite documentation for more information).
--descriptor/-d <descriptor>
- Create a new container including all the MiniApps listed in the Cauldron for the given complete native application descriptor
- Use this option if you want to locally generate a container that mirrors the container of a given native application version.
--devJsBundle
- Will generate a development JavaScript bundle rather than a production one.Default false
--fromGitBranches
- Create Container using the latest commits made to each of the MiniApp branches (HEAD), rather than using the MiniApps SHAs that are inside the current Container version.
- This flag is only used when creating a Container from a Cauldron descriptor
- This flag will be ignored if the target descriptor does not contain any MiniApps tracking git branchesDefault false
--miniapps/-m <miniapps>
- Create a new custom container including all the given MiniApps
- The MiniApps passed to this command can be a valid Yarn package format or a Git format or file scheme.
--platform/-p <android|ios>
- Specify the target platform for this container
- If not explicitly provided, the command prompts you to choose between the iOS or the Android platform before execution.
--outDir/--out <directory>
- Specify the directory to output the generated container to
- The output directory should either not exist (it will be created) or be empty
- Default If this option is not provided, the container is generated in the default platform directory
~/.ern/containergen/out
.
--ignoreRnpmAssets
- Inform the Container generator to ignore any rnpm assets optionally declared by MiniApps. This can be used in case you want to keep specific rnpm assets inside the native application itself and not the Container.
- This flag wil have no effect for a Container generated from a Cauldron as the Container configuration stored in the Cauldron will take precedence.
- Default Do not ignore rnpm assets and package them inside the generated Container.
--extra/-e
- Optional extra configuration specific to creating container
- Override some ios or android container generation configuration by passing
androidConfig
and/oriosConfig
attributes- As a json string For example
--extra '{"androidConfig": {"androidGradlePlugin": "3.2.1","buildToolsVersion": "28.0.3","compileSdkVersion": "28","gradleDistributionVersion": "4.6","minSdkVersion": "19","sourceCompatibility": "VERSION_1_8","supportLibraryVersion": "28.0.0","targetCompatibility": "VERSION_1_8","targetSdkVersion": "28"}}'
Find more information on android configurationor - As a file pathFor example
--extra <path>/container-config.json
In that case, the configuration will be read from the file. - As a Cauldron file pathFor example
--extra cauldron://config/container/container-config.json
In that case, the configuration will be read from the file stored in Cauldron.For this way to work, the file must exist in Cauldron (you can add a file to the cauldron by using the [ern cauldron add file] command).
- Optional hooks to run an arbitary script before or after js bundling is possible.
- If a script is defined as a
preBundle
hook, it will be executed after the composite generation, prior to running metro bundler, from the directory containing the generated composite project.- As a json string
--extra '{"containerGenerator": {"hooks": {"preBundle": "/workspace/ern/picking-miniapp/script/pre-script.sh"}}}'
- As a file path
--extra <path>/container-config.json
- As a Cauldron file path
--extra cauldron://config/config.json
- If a script is defined as a
postBundle
hook, it will be executed just after metro bundler has been run, from the directory containing the bundle.- As a json string
--extra '{"containerGenerator": {"hooks": {"postBundle": "/workspace/ern/picking-miniapp/script/post-script.sh"}}}'
- As a file path
--extra <path>/container-config.json
- As a Cauldron file path
--extra cauldron://config/config.json
Program to use to run the script should be indicated using shebang pattern in the script itself as first line.
--skipInstall
- Only used when generating an iOS Container with React Native >= 0.61.
- When set, skip
yarn install
andpod install
after generating the container. - default true on Windows/Linux, false on macOS
--sourceMapOutput
- Path to source map file to generate for this container bundle
--resetCache
- Indicates whether to reset the React Native cache prior to bundling
- Default false
- The
ern create-container
command can be used to create a container locally, for development, debugging and experimentation purposes. - Container generation and transformation/publication are separate processes (see
Related commands
section below for specific commands) - To create a container that is published so that your native application team can use the container, you should use one of the Cauldron commands to add your MiniApps to a specified native application version in the Cauldron, which will trigger the generation and publication of a Container. See Related commands.
