This section explains how to use the Sentinel Express SDK in offline mode |
What is offline mode?
Offline mode is a way to use the SDK without any internet access. It allows the SDK user to download necessary artifacts from OpenCloud’s online repository and push them into the user’s own local repository. The term 'local repository' is used to refer to a repository in the SDK user’s filesystem.
This document covers all of the steps required to create a local repository so that no internet connection is required. This can be useful for production environments or even in developer environments where internet access is limited or not available.
What is online mode?
When the SDK is not in offline mode, it is in online mode. In online mode, the SDK will connect to OpenCloud’s online repository to fetch required OpenCloud artifacts, rather than fetching from a local repository on the local machine.
The go-offline script
The go-offline script will create an offline repository and copy all artifacts to it. Note that this can take half an hour or more depending on connection speed.
The repository created by this script will be placed in the repositories directory in the root of the SDK.
Run the go-offline script:
testuser@machine$ build/bin/go-offline
$ ./build/bin/go-offline

Updating 'ivy.properties' to use offline resolvers:
ivy.sdk-resolvers.file=offline-resolvers.xml
ivy.cache.root=${sdk.root}/build/target/ivy-caches/offline-resolvers.cache
Configuration complete. SDK is now in 'offline' mode. Use 'go-online' to return to online mode.
The script will also have switched the SDK to offline mode now, so the next time the user starts the sdkadm tool it will use the new local repository.
After switching the SDK to offline mode, it is recommended to exit the sdkadm program before further use. Just type 'quit' and press enter.
The go-online script
The go-online script will switch the SDK to online mode.
