Multi-Region Deploy of Packaged Applications

In the current 5.6 Jelastic release, the regionlist field was provided with a possibility to select multiple environment regions, when preconfiguring a package installation. The following new optional parameters were added to support such integration:
  • multiSelect - allows selecting multiple regions (false by default)
  • min - sets the minimum number of regions required for the package installation (0 by default)
  • max - sets the maximum number of regions required for the package installation
  • required - makes the field obligatory for the provisioning (false by default)
  • delimiter - defines a delimiter for the multi-select (, by default)

multi region deploy
Note: The list field was also supplemented with the multiSelect and delimiter options, allowing to implement the similar to the above-described functionality for any custom list.

With such an improvement, it is possible to automate installations across multiple regions in a single package. For example, you can prepare a solution, which will create instances of your application in different regions, negating risks of unavailability.

Container Redeploy with Automatic Backups and Rollback on Failure

Container redeploy is a powerful tool to keep your software solutions up to date. Hoverer, there are always risks of your application or some specific configs incompatibility with the new container version. As a result, your project can become partially or entirely unavailable till the problem is resolved.

Aiming to eliminate even such a slight possibility, Jelastic PaaS developed a new algorithm for containers redeploy with the main innovation of creating a backup. In such a way, if an error occurs during container update, the platform automatically and painlessly restores node’s previous version, displaying the appropriate action in the dashboard task manager.

Here are some other specifics of the implementation:
  • you are not charged for the redeployment backups created by Jelastic
  • failure during the sequential redeployment interrupts the process so that it won’t be initiated on the remaining containers; the appropriate warning will be shown in the dashboard
  • if faced some problems after successful redeploy, contact your service hosting provider support team to restore the previously used container version (usually, only the latest redeploy operation can be reverted)

Custom IPv6 Firewall Rules

Most of the firewall configurations can be performed via the dedicated user interface, which allows configuring the inbound and outbound rules. Herewith, for more flexible management (for example, to configure NAT redirects), you can set custom firewall rules for your container.

In the current 5.6 platform release, the possibility to create custom rules for the IPv6 connects was implemented. Similarly to the flow implemented for IPv4, you need to define the required rules in the dedicated /etc/sysconfig/ip6tables-custom file (using the iptables-save tool format) and apply changes with the sudo /usr/bin/jem firewall fwstart command.

API Improvements

Adding Mount Point by IP Address

To support various project requirements, Jelastic PaaS implemented a possibility to add mount points via IP address instead of the domain name. The appropriate AddMountPointById and AddMountPointByGroup API methods were supplemented with the optional sourceAddressType parameter, which can be set as either DOMAIN (by default) or IP. The first option corresponds to the mount point binding by the domain name, while the second one - by IP address. Additionally, for the convenience of these methods usage, the protocol parameter was redefined as optional one and set to NFS by default.

Also, the GetMountPoints method was adjusted to return the appropriate sourceAddressType value in the response.

BindSSL Error Response Clarification

The BindSSL API method allows securing connection to an environment with a custom SSL certificate. As the task is not trivial, in the current Jelastic 5.6 upgrade, the error response was provided with the additional clarification details to simplify the debugging process for developers. For now, if a problem with custom SSL certificate addition occurs, the root cause can be discovered much quicker, and the whole issue resolved faster.

GitLab Deploy Tokens Support

The validation of the Login field in the deployment form was adjusted to provide the support of the Gitlab deploy tokens and allow quick and simple deployment from the repository without the necessity to configure authentication based on SSH key. Namely, the “+” and “-” special symbols, which are used in the generated by GitLab tokens (e.g. gitlab+deploy-token-1), were allowed.

Data Sharing: Export Config Validation

Jelastic allows you to share data between containers by exporting it on one node and mounting on the other using the NFS protocol. Herewith, if files should be exported to the external server, the appropriate /etc/exports configuration file should be manually adjusted. The automatic validation of the file content was implemented in the 5.6 platform upgrade to simplify the process for you. Namely, the duplicated records and the lines without options are commented by during a new export addition/removal. Also, the backup file of the original exports configurations is saved in the same /etc folder with the .backup-{date} extension.

Installation Packages with Limited Resources

Jelastic PaaS allows to proceed with the package installation (for example, from Marketplace or imported form JPS Collection) even if some of the account limits are lower than the ones stated in the manifest. Herewith, the appropriate notification is displayed on the installation frame:

jps with limited resources

Starting with the current 5.6 platform release, you can proceed with installation even if the package requires Jelastic SSL, which is not available for your account. Also, all of the cut resources are listed explicitly within the warning message at the bottom of the install confirmation frame.

In case any of the package requirements cannot be downscaled to match resources available for your account, the appropriate button to contact support is displayed (or the Upgrade now one for trial users).

UI/UX Improvements

Dashboard Functional Icons Renovation

Jelastic dashboard is a powerful GUI panel for the environments hosting and management. It provides access to the main functionality of the platform, allowing to comfortably manage all the aspects of your application lifecycle directly in the browser without the necessity of additional software installation. The most common operations are available through the context menu (displayed upon hovering over the environment, layer or node), where each element is presented in the form of the appropriate functional icon.

In the present 5.6 Jelastic release, these icons were restyled making them larger and more distinguishable.

Microservice Packages in Marketplace

Jelastic PaaS provides numerous pre-packaged solutions based on the microservices architecture, which are globally available via the Marketplace. In the present 5.6 platform release, the new Microservices section was added to the Jelastic Marketplace to group all of the relevant solutions (for example, Spring Boot Fat/Thin Jar Builder, Vert.x Fat/Thin Jar Builder, Docker Swarm Cluster).

Environment Groups Selection

Environment groups functionality allows organizing projects within your dashboard. Herewith, often you need to assign environment to just a single group, so, for now, the list is automatically collapsed after selecting an option. To choose multiple groups straight away, click on the required items while holding the Ctrl or Cmd key on the dashboard (the appropriate tip was added at the bottom of the form).

Custom SSL Dependencies Configuration

To secure an application with custom SSL, you need to correctly configure your environment topology and attach the appropriate custom domain (the one SSL certificate is issued for). The platform can automatically fulfill the topology requirements by including the certified application server or load balancer with the attached public IP. Just access the SSL section in the wizard and click the Enable button (is hidden if no reconfiguration is required).

custom ssl enable button

In the present Jelastic release, this button was visually upgraded to match the latest dashboard style. Also, the appropriate hint in the environment settings about custom SSL usage was updated as well.

Extended Description for the Unreachable NFS Error

The "Destination NFS server is not reachable" error was supplemented with the additional details to simplify analysis of the NFS related issues (i.e. with mount points and data export). Namely, the information on the target Server IP and the source Client IP was added to the response, allowing jump immediately into the investigation.
