# Infrastructure

To run CKBox on your server, you need to have certain services prepared first:

  • An SQL database (MySQL and Postgres are supported)
  • A Redis database
  • Data storage (S3, Azure Blob Storage, filesystem, MySQL, or Postgres)

Besides, you need an Open Container runtime to run CKBox. You can use, among others: Docker, Kubernetes, Amazon Elastic Container Service, or Azure Container Instances.

We also recommend using a load balancer. You can use almost any load balancer you choose, like NGINX, HAProxy, Amazon Elastic Load Balancing, or Azure Load Balancer. Thanks to this, you will be able to create TLS connections and run several cooperating instances of CKBox On-Premises. It will increase the security and the performance of the application.

# SQL Database

The SQL database stores persistent data like the configurations of categories, assets metadata, environments information, etc.

It can also be used as a data storage for your assets, but due to the SQL database limitations, the largest file you can send is 4GB. For this reason, we recommend using different storage drivers that can handle bigger files, like S3, Azure Blob Storage or a filesystem.


Minimum required version of MySQL is 5.7. The database and user should have at least the following privileges: ALTER, CREATE, DELETE, DROP, INDEX, INSERT, SELECT, TRIGGER, UPDATE, LOCK TABLES, REFERENCES.

If you plan using the MySQL database as a blob storage, increase the max_allowed_packet parameter:

set global max_allowed_packet = 209715200;

The database should be created before running Collaboration Server On-Premises. An example database creation script:

CREATE DATABASE `ckbox-on-premises`
  DEFAULT COLLATE utf8mb4_unicode_ci;

If you want to use another SQL database like Microsoft SQL Server, etc., please contact us.

If binary logging is enabled without the SUPER privilege, please make sure that log_bin_trust_function_creators is enabled. Check your configuration, especially when you use a managed database service (DBaaS) like AWS RDS/Aurora, Azure Database, Google Cloud SQL or DigitalOcean Managed Databases.

# PostgreSQL

Minimum required version of PostgreSQL is 12.0. The database and user should have at least the following privileges: SELECT, INSERT, UPDATE, DELETE, REFERENCES, CREATE, USAGE.

The database with a schema should be created before running Collaboration Server On-Premises. An example database and schema creation script:

\connect "cksource";
CREATE SCHEMA "ckbox-on-premises";

# Running the service

After meeting all infrastructure requirements, you can prepare the CKBox application to run.
