#### Default image change for Redis Enterprise Software containers
102
+
103
+
Starting with version 7.6, Redis Enterprise Software containers with the image tag `x.y.z-build` will be based on RHEL instead of Ubuntu.
104
+
105
+
This change will only affect you if you use containers outside the official [Redis Enterprise for Kubernetes]({{<relref "/operate/kubernetes">}}) product and use Ubuntu-specific commands.
106
+
107
+
To use Ubuntu-based images after this change, you can specify the operating system suffix in the image tag. For example, use the image tag `7.4.2-216.focal` instead of `7.4.2-216`.
