Docker build for system service fails on features.sh

[stefandecimelli]

Issue encountered when running in the start folder.

To reproduce:

sudo docker build -t system:1.0-java11-SNAPSHOT --build-arg JAVA_VERSION=java11 system/.
failure also present on
sudo docker build -t system:1.0-java17-SNAPSHOT --build-arg JAVA_VERSION=java17 system/.

This is not seen when building the graphql container with docker build -t graphql:1.0-SNAPSHOT graphql/.

Temporary solution seems to be to edit system/Dockerfile to use the docker base kernel-slim- rather than full-

ARG JAVA_VERSION=java11
ARG VERSION=1.0
ARG REVISION=SNAPSHOT
FROM icr.io/appcafe/open-liberty:full-${JAVA_VERSION}-openj9-ubi
...

to

ARG JAVA_VERSION=java11
ARG VERSION=1.0
ARG REVISION=SNAPSHOT
FROM icr.io/appcafe/open-liberty:kernel-slim-${JAVA_VERSION}-openj9-ubi
...

hi @decimelli

Thank you to report this issue. It is because the full image does not need to call features.sh to install Liberty features, that why it does not provide features.sh. If you include it in the Dockerfile, it will have the error as you reported.

Yes, the system service in this guide should either remove the features.sh or change to use kernel image. We will fix it.

the issue relates to OpenLiberty/ci.docker#469

• the issue was fixed that the system Dockerfile uses the kernel-slim image now
