Provider Types ​

Tsuru supports multiple SDK provider types. This page documents the available providers and their specific features.

JDK (Java Development Kit) ​

The JDK provider allows you to install and manage different Java Development Kit distributions.

Available Vendors ​

JDK requires explicitly specifying a vendor:

Zulu ​

Azul Zulu is a certified build of OpenJDK that is fully compliant with the Java SE standard.

bash
# Install Zulu JDK
tsuru install jdk zulu 21

GraalVM Community Edition ​

GraalVM Community Edition is a high-performance JDK distribution.

bash
# Install GraalVM Community Edition
tsuru install jdk graalcommunity 24

Version Format ​

For JDK, you can specify versions in the following formats:

  • Major version only: 21, 17, 11
  • Major.Minor: 21.0, 17.0.8
  • Full version: 21.0.1+12

Tsuru will find the latest matching version that satisfies your request.

Environment Variables ​

When using a JDK, Tsuru sets the following environment variables:

  • JAVA_HOME - Points to the root directory of the JDK installation
  • PATH - Updated to include the JDK's bin directory

NodeJS ​

The NodeJS provider allows you to install and manage different versions of Node.js.

Version Format ​

For NodeJS, you can specify versions in the following formats:

  • Major version only: 20, 18, 16
  • Major.Minor: 20.1, 18.16
  • Full version: 20.1.0

Environment Variables ​

When using NodeJS, Tsuru sets the following environment variables:

  • NODE_PATH - Points to the root directory of the NodeJS installation
  • PATH - Updated to include the NodeJS bin directory

Provider Selection ​

When installing or using a provider, you need to specify the provider type and, if applicable, the vendor:

bash
tsuru install <provider> [vendor] <version>

For providers that don't require an explicit vendor (like NodeJS), you can omit the vendor:

bash
tsuru install nodejs 20

For providers that do require a vendor (like JDK), you must specify it:

bash
tsuru install jdk zulu 21
