Web SSH Performance Optimization

Within the present platform upgrade, the performance of the recently implemented Web SSH feature was boosted. This was achieved by adding special PageSpeed module, which automatically compresses data within requests, combines all scripts and css files into a single one (to reduce a number of requests), etc. As a result of such optimization, the authentication for Web SSH client is performed notably faster and the overall performance of the tool is improved.

Waiting for NFS Server during Mount Points Creation

In case a new mount point addition is called during NFS server unavailability (e.g. creation or restart), the appropriate error immediately occurs. In the current Jelastic 5.4.8 version, a dedicated timeout was added before reporting an issue, which allows NFS to start up and process the request. Herewith, the operation is retried every 4 seconds for 5 times, giving a total of the additional 20 seconds for the mount point to be successfully created.

Auto-Refill Adjustment

Jelastic auto-refill feature allows to configure regular payments to keep your account active and all of the comprised environments running. The available frequency (condition) options are:
  • Weekly (every Monday)
  • Monthly (1st of each month)
  • Balance is less than a specified sum

Starting with the current 5.4.8 Jelastic upgrade, the latter option will additionally consider account bonuses. In such a way, an automatic refill is triggered only in case the combined value of the account balance and bonuses is less than the specified number.

Notification about Failed Installation of Packages in Containers

When creating a custom Docker container, platform automatically installs a number of basic packages (e.g. openssh-server, cron, curl, etc) to ensure a proper node operability within Jelastic PaaS. Herewith, depending on the selected image, the installation of certain packages may fail, resulting in the probable issues during this container management in the future. So, starting with the present 5.4.8 platform upgrade, in case of such a problem, the appropriate notification will be sent to the node owner, providing a list of not installed packages.

CentOS VPS Adjustments

CentOS is a popular virtual private server and Jelastic provides a managed template of this software stack. Starting with the current 5.4.8 platform release, its in-built anyterm Web-based SSH client was completely removed from the template due to a newer, more powerful and convenient Web SSH tool integration on the platform.

Email Templates Update

Within the present Jelastic upgrade, the following adjustments were applied to some of the email notifications:
  • the platform links within emails (e.g. in the Environment transfer request one) were tuned to correctly detect http or https protocol, utilizing the former one only in case the SSL is not configured for the current Jelastic installation
  • an email template for the custom Docker containers was adjusted to provide better clarity and greater usability:
    • credentials for SSH access were explicitly denominated as SSH Login and SSH Password to avoid any misunderstanding
    • Access URL field was replaced with the Host Name one (i.e. node link without the protocol part), which is required more frequently

Suppressing Warning for Ruby Bundler

The Apache Ruby and NGINX Ruby software stacks are provided with the Bundler dependency manager out-of-box in Jelastic. It helps to comfortably manage your project dependencies and ensures the gems you need are present. While working with Bundler, a warning about running it under the root user was displayed. Message notified about the potential issues of such approach, which, in case of Jelastic PaaS, are irrelevant. So, in order to avoid confusion and unnecessary concerns, this warning was removed, allowing to provide a clearer response for operations with Bundler.
