During the export, all information about environment (i.e. its topology settings, deployed applications, links to the archives with configurations and private data it contains, etc) is packed into a single .json file. This compact JSON package can be simply downloaded to your local computer for being stored and/or deployed at another Jelastic platform.
So in order to export a copy of your environment, log into your Jelastic account and follow the instruction below:
1. Select Settings button for the environment you would like to export (named my-application in our case).
Note that environment should have the Running status for being exported.
2. In the opened Settings tab, navigate to the Export section and click on the same-named button.
3. Within the appeared Environment Export dialog, you can choose which data should be exported (tick all options to get the fully identical environment copy):
- Topology Settings - environment configurations you’ve set through the Environment topology wizard (this point is obligatory and enabled by default)
- Private Data - files in directories of your deployed application(s) and private data stored within your database server(s)
- Configuration Files - all files, accessible via Configuration Manager at your dashboard, and settings of the deployed GIT/SVN projects (e.g. repositories links, access credentials, attached private SSH keys, etc)
Note: For ensuring your application and data safety, it is highly recommended not to delete original of the exported environment until its copy is successfully imported to another platform.
Once the required for export data is defined, click the Export button to proceed.
Depending on the type of containers your environment contains, you should take into account the following points:
- Data from Elastic VPS, Maven, Docker and Windows-based containers won’t be exported, though they will be still included to the topology of your imported environment (i.e. created from scratch), so you’ll be able to reconfigure these servers manually afterwards
- When exporting an NGINX server (of both load balancer or application server node types), the appropriate node will be briefly stopped and automatically started again to fetch a server dump
- Private SSH key, exported alongside with the rest of GIT repository settings, can’t be deleted from the imported environment and is not shown at the dashboard, though it will still be used for connection. Nevertheless, it will be substituted if choosing a new one within the GIT project’s settings window
4. Once the export is successfully finished, a new clickable string (named due to the export time/date) will appear in the Exported Environment Copies list. Select it to download the compiled .json file with exported environment data to your local machine, or just right click on it to copy direct URL to this manifest (which can be also used during import).
In addition, you’ll receive the appropriate email notification with link to the list of your exported environments.
You can create as many exported environments’ archives as you need, but note that all of them will be stored in your disc space, which is charged according to your hosting service provider's tariffs. If a particular file is no longer needed, you can delete it by means of clicking the red cross button right before the corresponding string.
That’s all! You have successfully exported your environment copy. Now, you can proceed to its importing to the target platform in order to complete the migration.
