## What is a Container Image { #what-is-a-container-image }

A **container** is run from a **container image**.

A container image is a **static** version of all the files, environment variables, and the default command/program that should be present in a container. **Static** here means that the container **image** is not running, it's not being executed, it's only the packaged files and metadata.

JDK 16 is required to build Elasticsearch. You must have a JDK 16 installation
with the environment variable `JAVA_HOME` referencing the path to Java home for
your JDK 16 installation. By default, tests use the same runtime as `JAVA_HOME`.
However, since Elasticsearch supports JDK 11, the build supports compiling with
JDK 16 and testing on a JDK 11 runtime; to do this, set `RUNTIME_JAVA_HOME`
