Other implementations

• testcontainers-iris-java

Basic usage

>>> from testcontainers.iris import IRISContainer
>>> import sqlalchemy
>>> iris_container = IRISContainer("intersystemsdc/iris-community:latest")

>>> with iris_container as iris:

...     engine = sqlalchemy.create_engine(iris.get_connection_url())

...     with engine.begin() as connection:

...         result = connection.execute(sqlalchemy.text("select $zversion"))

...         version, = result.fetchone()

>>> version

'IRIS for UNIX (Ubuntu Server LTS for ARM64 Containers) 2023.2 (Build 227U) Mon Jul 31 2023 17:43:25 EDT'

The snippet above will spin up a InterSystems IRIS database in a container. The get_connection_url() convenience method returns a sqlalchemy compatible url we use to connect to the database and retrieve the database version.

It is possible to run Enterprise edition as well, with passing a valid iris.key.

iris_container = IRISContainer(
    "containers.intersystems.com/intersystems/iris:2023.3", 
    license_key="/full/path/to/iris.key",
    username="testuser",
    password="testpass",
    namespace="TEST",
)

username, password, namespace will be created during start of the container with required values, user will get %All role
