Jelastic 4.9.5

This document is preliminary and subject to change.

In this document, you will find all of the new features, enhancements and visible changes included in the Jelastic PaaS 4.9.5 release:

For detailed information on using any of Jelastic features, please refer to the users’ documentation.

Tomcat 9 Support

Tomcat 9 (alpha stage currently) represents the latest release of the Apache Tomcat application server, which includes multiple changes and bug fixes (see the official changelog for details). Among the most notable treats, it runs only Java 8 engine and implements Servlet 4.0 version. Also, Tomcat 9 utilizes the latest Java specifications: JSP Spec 2.4, EL Spec 3.1 and WebSocket Spec 1.2 (the exact versions may be changed after the stable release). All of this ensures smooth and comfortable user experience during your Java apps development.

Jelastic delivers Tomcat 9 in a form of OpenShift-based cartridge and was integrated to all Platforms starting from Jelastic 4.2 version. Herewith, similar to the rest of custom stacks, its availability at every particular cluster installation depends on hosting service provider settings.

Ubuntu Support for Elastic VPS

Elastic Virtual Private Server represents a bare independent virtual machine. Extending the number of supported OS distributions for this kind of stack, the present Platform upgrade includes provision of Jelastic-certified Ubuntu template for VPS hosting. The exact version of delivered OS distribution is the latest stable Ubuntu 16.04 release. This allows you to get all the functionality of isolated scalable VPS, simultaneously enhanced with Ubuntu performance capabilities.

Just as the rest of virtual private servers, Ubuntu-based VPS instance can be created right through the corresponding VPS section of the environment wizard. Herewith, unlike CentOS and Windows-based VPS instances, this stack doesn’t provide the inbuilt web interface for its management. Thus, all of the configurations should be applied through connecting to a node via SSH, where the full root permissions are granted.

Export/Import for Docker & Windows Containers

In confines of Jelastic 4.9.5 release, the environment export/import feature support was implemented for Docker- and Windows-based containers. From now on, you can effortlessly move environments containing such instances across Jelastic cloud hosting partners platforms.

Similarly to the Storage, VPS and Maven nodes, both Docker and Windows containers are created from scratch when migrated (in accordance to the exported environment topology). Herewith, imported containers won’t include any custom data (i.e. the appropriate Private Data and Configuration File options are disabled for selection within export frame). So, if needed, you should apply the corresponding changes and integrate the needed data manually afterwards.

The main Docker containers settings (such as variables, links, local volumes and run configs) will remain applied to containers at a new environment location. They are set the same for all instances within the appropriate environment layer based on the master node settings.

Note: Currently, exported environment copies with mount points from other environments or external sources can not be imported to a different Jelastic installation. This possibility will be implemented in future releases.

Also, while moving Docker container that was deployed from a custom registry, the authentication data (username and password) won’t be transferred due to security reasons. Thus, in order to successfully import such environment, you need to preliminary specify these credentials within the appropriate exported manifest file.

Extended Custom SSL Support

Jelastic 4.9.5 release includes extension of the list of servers, that support ability to attach custom SSL certificates, with a number of custom stacks. Namely, GlassFish 4Tomcat 8 and Tomcat 9 templates were updated (Jetty 9 will be added shortly). So, the appropriate newly created containers will support automatic appliance of the HTTPS traffic encryption directly via user dashboard (whilst the already existing containers won’t be patched to get this possibility).

In case any of the above mentioned stacks is not available at a Platform you use, appeal to your hosting provider and request its addition.

Increased IO Performance for Dedicated  Storage Container

In the current 4.9.5 Platform upgrade, another major update was applied to the Dedicated Storage Container in order to implement usage of more fast and optimized Kernel Based NFS server instead of the FUSE one. This grants notable boost of server performance, increasing efficiency and user-appeal of the solution.

The new functionality will be automatically provided for the newly created Storage containers. In order to update the existing ones, the corresponding environment should be entirely stopped and then started again (i.e. not through just restarting a particular node) to apply the required changes.

Logging of Collaborators Actions

Jelastic account collaboration is substantial and highly valued by developers feature, as it allows to access a single environment from different accounts (e.g. organization units). Herewith, provided privileges can be tuned for each user separately by assigning one of the roles: viewer with general access permissions and admin with ability to change environment topology and full SSH access.

Starting with 4.9.5 Jelastic version, environment owner is provided with information on all actions, applied to it by other collaboration participants. This is ensured with a special User column, added to the Tasks manager dashboard panel. It is shown only for owners (creators) of shared environments and provides email of the collaborator the changes were made by.

UI/UX Improvements

File Manager
Task Panel
JPS Import Examples

File Manager

Jelastic configuration manager provides an easy access to the container file system through the dashboard. This allows to apply some common configurations right via your browser with no additional tools required.

Here are a few improvements that were implemented to configuration manager within the current Platform upgrade in order to make it even more user-friendly:
  • the path string above filesystem tree is now displayed without ROOT at the beginning, in such a way designating the location relatively to this main directory
  • location of the currently selected file or folder is automatically added to the path bar at the top, allowing to easily define where it’s placed and copy path to it
  • the Additionally actions list was complemented with the new Copy Path option, that will add it to the clipboard
  • the return option (in a view of backward arrow) was added to the beginning of file list, allowing to move one level up within file tree
  • for the opened files, the Refresh button was moved to the left (next to the Search one), while the full file path is now displayed within the remaining panel part

Task Panel

As a part of the dashboard interface, Tasks panel is used to monitor and analyze actions performed by Jelastic Platform. Obviously, the displayed here data should be easily perceived. Thus, for now the list won’t jump up to display the currently ongoing action during scrolling down and exploring other tasks, granting better user experience.

Also, some changes were applied to the minimized Tasks panel mode (can be enabled with the doubled down arrow at the top-right corner of the section). Upon this panel folding, the remained single row will show the following information according to the amount of active actions:
  • multiple tasks - shows the number of currently performed actions (e.g. 5 active tasks)
  • one task - gives description for this ongoing action (e.g. Adding Nginx 1.10 node to {environment name})
  • no tasks - displays the idle status label (i.e. No active tasks)

JPS Import Examples

Jelastic import is a highly demanded feature that allows to install any JPS package (i.e. JSON manifest file with environment or add-on description) right through the dashboard. This time, in order to improve the package delivery process, the new Examples link was added to the Import frame.

Upon selecting it, you will be redirected to the Jelastic JPS Collection page, which offers numerous ready-to-go packages and add-ons. This way, you can find the most suitable solution according to your needs or just explore them for being used as a basis for your own sample.

API Improvements

“Get” Methods for Maven Build Node
Returning Node Domain Name as Part of Endpoint Data


“Get” Methods for Maven Build Node

The Jelastic 4.9.5 release also includes new GetProjects API method, aimed to simplify remote Java VCS projects management. This request allows to fetch list of all projects, added to a Maven build node, and operates the following parameters:
  • session (string) - is used to check user authentication
  • envName (string) - selects the target environment
  • nodeGroup (string) - points to the environment layer (use the “build” one)
  • nodeId (integer) - numerical identifier of the container

Also, another GetProjectInfo method was supplemented with a new projectName parameter, which allows to get information about the project by its name, shown in the dashboard (rather than only by its unique ID, which should be additionally fetched with the GetProjects, getEnvs or getEnvInfo method).

Returning Node Domain Name as Part of Endpoint Data

In the present 4.9.5 Jelastic release, responses of the API methods that provide information on attached endpoints were extended with additional field. It was added to return the corresponding node(s) domain name alongside with the information on listened public and private ports.

Namely, the AddEndpoint request and, in case of the attached endpoints presence, responses for the GetEnvInfo and GetEnvs calls were enhanced. This allows to get the whole node access URL much easier through combining domain name with the corresponding public port value.

Engines & Supported OS Updates

The regular software stacks renovation, performed upon each Platform release, this time includes the following notable updates:
  • the major PHP 7.0 version was updated to the 7.0.13 release, which replaced the preceding 7.0.10 one to fix the number of bugs and security issues
  • the most recent PHP 7.1 engine was integrated to Platform as well, providing numerous improvements and major features that can be explored within official documentation
  • to support out-of-box interconnection between Apache Python application server and PostgreSQL database, we’ve added the dedicated postgresql-devel package to the appropriate app server template
    Note: This improvement is compatible since 4.6 Jelastic version, so all newly created Python containers at such Platforms will include the postgresql-devel package. If being needed for the legacy (i.e. the already existing) servers, it still should be installed manually.
  • the latest releases of Fedora 25 and Ubuntu 17.04 were added to the list of supported OS for Docker containers

As usual, the full list of the most recent software stack versions, included to the present Jelastic release, can be checked within the corresponding section below.
