What PostgreSQL clients are available through microdnf install? I'm trying to install a client via my Dockerfile.

I've tried multiple commands I've seen recommended and several guesses, but none of them worked for me:

microdnf install -y postgresql-client
microdnf install -y postgresql
microdnf install -y psql
etc.

PS = Is there a website I can go to to see the full list of packages available?

I have the same issue, but with maven docker image (it based on OracleLinux 8).

Oracle Linux 8 & Postgresql13 Client

It was extremely unusual to install postgresql client on it, so, let's consider my steps:

  1. https://www.postgresql.org/download/linux/redhat/
    Select RHEL 8 and receive the rpm package link

  2. Install it manually with rpm

microdnf install -y wget
wget https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm -O /tmp/pg_repo.rpm
rpm -i /tmp/pg_repo.rpm

  1. Determine that there is no postgresql13 package. Click on the direct download link and select RHEL 8: https://download.postgresql.org/pub/repos/yum/13/redhat/rhel-8-x86_64/

  2. Download postgresql13-13.x.x... package (latest)

wget https://download.postgresql.org/pub/repos/yum/13/redhat/rhel-8-x86_64/postgresql13-13.3-2PGDG.rhel8.x86_64.rpm -O /tmp/pgql.rpm

Dependency list for that rpm:

libicu is needed by postgresql13-13.3-2PGDG.rhel8.x86_64
        libpq.so.5()(64bit) is needed by postgresql13-13.3-2PGDG.rhel8.x86_64
        postgresql13-libs(x86-64) = 13.3-2PGDG.rhel8 is needed by postgresql13-13.3-2PGDG.rhel8.x86_64
        systemd is needed by postgresql13-13.3-2PGDG.rhel8.x86_64
        systemd-sysv is needed by postgresql13-13.3-2PGDG.rhel8.x86_64
  1. Install dependencies
microdnf install -y systemd postgresql13-libs libicu
  1. Finally, install the client
rpm -i /tmp/pgql.rpm

Now you can clear the cache and test the client, e.g. pg_dump command.

Result Dockerfile command:

RUN microdnf install -y wget && \
    wget https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm -O /tmp/pg_repo.rpm && \
    rpm -i /tmp/pg_repo.rpm && \
    microdnf install -y systemd postgresql13-libs libicu && \
    wget https://download.postgresql.org/pub/repos/yum/13/redhat/rhel-8-x86_64/postgresql13-13.3-2PGDG.rhel8.x86_64.rpm -O /tmp/pgql.rpm && \
    rpm -i /tmp/pgql.rpm && \
    rm -f /tmp/pg_repo.rpm /tmp/pgql.rpm && \
    microdnf remove -y wget

RHEL 8 & Postgresql13 Client (your case)

Now let's consider your case, image jboss/keycloak:14.0.0 based on RHEL 8.

Caveat: If you receive error message error: Failed to create: /var/cache/yum/metadata, run as root user and than switch user back to jboss.

All steps and Dockerfile commands are the same.

Please, let me know if there are any mistakes or something is not well-described.

  • @Tliak - I tried several ways of running as root (sudo & the like), but commands didn't exist. How would I execute as root in a standard keycloak container. – ScrappyDev Dec 10 '21 at 13:33

It's working for me on with a Dockerfile based on openjdk:15.

FROM openjdk:15.0.1-oracle
...
RUN microdnf update
RUN microdnf module enable postgresql:13
RUN microdnf install postgresql.x86_64
