WebSphere Liberty container images are available from the IBM Container Registry (ICR) at icr.io/appcafe/websphere-liberty. Our recommendation is to use ICR instead of Docker Hub since ICR doesn't impose rate limits on image pulls. Images can be pulled from ICR without authentication. Only images with Universal Base Image (UBI) as the Operating System are available in ICR.
The images for the latest Liberty release and the last two quarterly releases (versions ending in .3, .6, .9 and .12) are available and are refreshed regularly (every 1-2 weeks) to include fixes for the operating system (OS) and Java.
Available image tags are listed below. The tags use the following naming convention. For more information on tags, see Container image naming conventions documentation.
<optional fix pack version-><liberty image type>-<java version>-<java type>-<base image type>
Liberty images with Java 21 are based on UBI 9 minimal and include IBM Semeru Runtimes for Java 21 JRE. This combination offers a compact and effective Java runtime that is suited for applications that need Java 21.
Liberty images with Java 8, 11 and 17 and with the openj9 type are based on UBI 8 standard and include IBM Semeru Runtime for the respective Java version with the JDK. Images with the ibmjava type are based on UBI 8 standard and include IBM Java 8 JRE.
The latest tag simplifies pulling the full latest Open Liberty release with the latest Java JRE. It is an alias for the full-java21-openj9-ubi-minimal tag. If you do not specify a tag value, latest is used by default.
Append a tag to icr.io/appcafe/websphere-liberty to pull a specific image. For example,
icr.io/appcafe/websphere-liberty:24.0.0.12-kernel-java17-openj9-ubi
Available images can be listed using IBM Cloud CLI. Log in with your IBMid prior to running the following commands. Note that authentication is only required to list the images. Images can be pulled from ICR without authentication :
ibmcloud cr region-set global
ibmcloud cr images --restrict appcafe/websphere-liberty
