Will this change the commands from zpm to ipm?

In your docker build try this sequence:

USER root
RUN apt-get clean -yq && apt-get update -yq && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends openjdk-11-jdk
USER ${ISC_PACKAGE_MGRUSER}

Or install sudo (very bad practice in containers):

USER root
RUN apt-get clean -yq && apt-get update -yq && DEBIAN_FRONTEND=noninteractive apt-get install -y --no-install-recommends tzdata curl gnupg ca-certificates sudo
RUN /bin/echo -e ${ISC_PACKAGE_MGRUSER}\\tALL=\(ALL\)\\tNOPASSWD: ALL >> /etc/sudoers
RUN sudo -u ${ISC_PACKAGE_MGRUSER} sudo echo enabled passwordless sudo-ing for ${ISC_PACKAGE_MGRUSER}
USER ${ISC_PACKAGE_MGRUSER}

Health Connect is containerized already and should have feature parity with InterSystems IRIS and IRIS for Health.

See here for some examples: https://github.com/kuszewski/iris-k3s

In the iko yaml files, you can change the iris tags to healthconnect and it works seamlessly.
