Full list of ContainerTemplate schema properties

You can set custom security context and environment variables for a container.

The environment variables are defined under the env property as a list of objects with name and value fields. The following example shows two custom environment variables and a custom security context set for the Kafka broker containers:

# ...
template:
  kafkaContainer:
    env:
    - name: EXAMPLE_ENV_1
      value: example.env.one
    - name: EXAMPLE_ENV_2
      value: example.env.two
    securityContext:
      runAsUser: 2000
# ...

Environment variables prefixed with KAFKA_ are internal to Streams for Apache Kafka and should be avoided. If you set a custom environment variable that is already in use by Streams for Apache Kafka, it is ignored and a warning is recorded in the log.
