 How to get the software

InterSystems IRIS 2021.2 is a Continuous Delivery (CD) release, which now comes with classic installation packages for all supported platforms, as well as container images in OCI (Open Container Initiative) a.k.a. Docker container format.  Container images are available for OCI compliant run-time engines for Linux x86-64 and Linux ARM64, as detailed in the Supported Platforms document.

Full installation packages for each product are available from the WRC's product download site for CD releases. Using the "Custom" installation option enables users to pick the options they need, such as InterSystems Studio and IntegratedML, to right-size their installation footprint.

Container images for the Enterprise Edition, Community Edition and all corresponding components are available from the InterSystems Container Registry using the following commands:

docker pull
docker pull
docker pull
docker pull

For a full list of the available images, please refer to the ICR documentation.

Alternatively, tarball versions of all container images are available via the WRC's product download site for CD containers.

Our corresponding listings on the main cloud marketplaces will be updated in the next few days.

Hi Ben.

For some reason, only IRIS 2021.1CE is available for Windows, although IRIS 2021.2CE is available for many other operating systems, such as MacOSX.

Is it possible for Windows to update the version to 2021.2 too?

@Vitaliy.Serdtsev - thank you very much for bringing this to our attention!  There was a small issue resulting in the version listing being out of date.  This has been corrected and you should be able to get access to 2021.2 for Windows now (please let me know if you still have issues).  Thanks for reaching out!

Now on for Windows/MacOSX/Container allows to download the version of IRIS 2020.1CE, and for the rest - IRIS 2021.2CE.

What happened and when will the problem with downloading the latest version disappear once and for all?

This is a bug. We'll look into it. Thank you for bringing it to our attention.

And images with ZPM package manager 0.3.2 are available accordingly:


And to launch IRIS do:

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/iris-community:2021.2.0.651.0-zpm

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/iris-ml-community:2021.2.0.651.0-zpm

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/iris-community:2021.2.0.651.0-zpm

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/irishealth-community:2021.2.0.651.0-zpm

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/irishealth-ml-community:2021.2.0.651.0-zpm

docker run --rm --name my-iris -d --publish 9091:1972 --publish 9092:52773 intersystemsdc/irishealth-community:2021.2.0.651.0-zpm

And for terminal do:

docker exec -it my-iris iris session IRIS

and to start the control panel:


To stop and destroy container do:

docker stop my-iris

And the FROM clause in dockerfile can look like:

FROM intersystemsdc/iris-community:2021.2.0.651.0-zpm

Or to take the latest image:

FROM intersystemsdc/iris-community

Please change all the 649's in this to 651 - 2021.2 was republished

Updated to 651, thanks, @Jeffrey Fried!

Also, we have the latest tag for ZPM images, so this will take the latest:

FROM intersystemsdc/iris-community:latest

Or just like this:

FROM intersystemsdc/iris-community

Are there any news on docker hub publication?

docker pull store/intersystems/iris-community:2021.2.0.649.0
Error response from daemon: manifest for store/intersystems/iris-community:2021.2.0.649.0 not found: manifest unknown: manifest unknown

InterSystems IRIS 2021.2 is now available on docker hub, you can retry that command.

However, due to Docker changing the terms of licensing, InterSystems is phasing out its Community version listings on docker hub after January 31, 2022.

In the future, we may have a listing there, but that is not finalized.

Currently, as well as in the future, these images can be obtained with docker CLI via:

docker pull

Note that does not require authentication when pulling Community Edition (CE) of InterSystems IRIS (see InterSystems Container Registry). Stay tuned for an announcement about our plans for docker hub, and please let us know if you have concerns or questions!

docker pull

is probably

docker pull

Interesting news. Question: as access to requires a WRC account, how do prospects/new users/people without WRC access can get community version of InterSystems IRIS?

Thanks, Eduard! I updated the above comment to fix the typo!

The Community Edition (CE) of InterSystems IRIS are available from without credentials. This should work for anyone:

docker pull

UPDATE! We discovered a defect in the Windows builds of InterSystems IRIS 2021.2, and have now updated those images on the WRC download site for Continuous Delivery releases. The new build number for the Windows kits is 651.
