Packages

Big Bang includes many different packages that provide services to the ecosystem. Each of these packages is deployed by a Helm chart located in a repository under Big Bang's Universe Group. The packages are broken up into several categories listed below. Sometimes packages are tightly coupled and grouped together in a stack. When using a stack, all packages in the stack will be deployed.

    • Developer Tools
  • Further Information

Technical Oversight Committee (TOC)

The Big Bang TOC supports users and contributors of the Big Bang ecosystem. If you would like to add, modify, or remove packages in Big Bang, we encourage you to attend the TOC to discuss your ideas. You can find details in the BBTOC repository.

Dependency Tree

Several of Big Bang's packages have dependencies on other packages. A Dependency exists if the package would have a significant (or total) loss in functionality if the dependency was not present.

Footnotes:

• Dotted lines in Core indicate a package that is not enabled by default
• The following were left off the chart to keep it simple
  • Most packages depend on Istio for encrypted traffic and ingress to interfaces.
  • Some packages have operators that are deployed prior to the package and manage the package's state.
