BitssCloud 6.0

In this document, you will find all of the new features, enhancements, and visible changes included in the BitssCloud PaaS 6.0 release.

New Features:

     1. Non-Downgradable Software Stacks

BitssCloud PaaS provides out-of-the-box support for multiple software stacks to build topologies that meet the most demanding users’ requirements. Moreover, most of the stacks have at least a few releases to choose from. These versions can be freely switched at any time due to the Containers Redeploy feature.

However, not all the software solutions provide backward compatibility. If there are substantial differences between the releases, downgrading a software version can result in unforeseen problems. In the current BitssCloud 6.0 upgrade, all the stacks were analyzed to locate those vulnerable to the issue and explicitly restricted from downgrading during the redevelopment process.

Currently, redeployment to the lower version is forbidden on the following stacks:

  • MariaDB
  • MongoDB
  • MySQL
  • Percona
  • PostgreSQL
  • Couchbase

     2. Extended Target Node Filtering in Cloud Scripting

The targetNodes parameter is an optional config for the JPS add-on solutions that defines environments suitable for installation. In the current BitssCloud 6.0 release, its functionality was extended with an additional guestOSType filter, which lists the suitable OS templates for the add-on installation. The possible values are:


Changed Features:

     1. Traffic Distributor Package Update

Traffic Distributor is a package powered by BitssCloud, which helps control traffic flow between environments. It is an easy-to-manage solution suitable for multiple use cases and hosting scenarios (Blue-Green DeployFailover ProtectionA/B Testing). In the present 6.0 BitssCloud upgrade, BitssCloud Team integrated the ability to choose between proxying traffic to backends over SSL or without it. The corresponding HTTPS config within the Traffic Distributor package UI is shown in the image below:

Also, the default value for the proxy_connect_timeout setting in Traffic Distributor was increased to 60 seconds to reduce the number of reconfigurations due to the false-positive backend failures. However, upon selecting the Failover routing method, this parameter is automatically changed to the 20 seconds value.

     2. Extended Logs in Tasks Manager

Dashboard’s tasks manager provides all the vital information on the account activities. It helps developers with troubleshooting, issues analysis, and action tracking. In the current 6.0 BitssCloud release, the tasks manager was improved by providing additional log information for errors. This log field is present in the response of some error messages and contains valuable data for debugging.

     3. No Free Disk Error Clarification

BitssCloud PaaS has two types of the “No free disk space” error. The first one relates to the particular node and can be handled by the container owner. The second one reports the disk space shortage on the host (hardware server), which can only be resolved by the service hosting provider. In the present 6.0 upgrade, additional clarifications were added to separate such issues in the dashboard and provide correct resolution steps, i.e. either to increase disk space or contact support.

     4. Binding Busy Domain Error Clarification

In the current BitssCloud 6.0 upgrade, a validation message for the binding of a custom domain that is already used by some other environment on the platform was improved. For now, instead of a general error, it explicitly notifies that the specified domain is already in use. Moreover, if an external domain belongs to the same account, the error message will point to the appropriate environment.

     5. Run.log Logrotate

Logrotate is a standard UNIX rotation and compression tool for log files. BitssCloud PaaS automatically rotates all the main log files on the containers to ensure efficient disk space utilization without losing any crucial information from the log files. In the present 6.0 platform release, the run.log file was added to the list of logs that should be automatically rotated by the system.

     6. API Changes

Below, you can find a list of all changes to the public BitssCloud API in the 6.0 platform version (compared to the preceding 5.9.8 ones):

  • added new GetSetSLBAccessEnabledSetOptions, and ApplyData methods to the nodegroup service
  • added a new GetNodeTags method to the control service
  • added the lang optional parameter to the RecoverPassword method from the account service
  • changed the search parameter to mandatory for the SearchActions method from the tracking service

Also, all the deprecated methods were explicitly marked in the API documentation.


     1. CentOS 6 End-of-Life

CentOS 6 software stack support has officially reached its end-of-life. It will no longer get any updates and security fixes. In order to ensure that BitssCloud users operate with reliable and secure stacks only, CentOS 6 was removed from the list of supported OS templates on the platform. After the 6.0 upgrade, the creation of the new containers based on the CentOS 6 will not be possible, while any existing instance will remain fully operable. However, we strictly recommend updating to the 7th or 8th release versions via built-in redeploy functionality.
