Debezium error : yum: command not found returned a non-zero code: 127

[Hernaldo A González]

Help. I'm Stuck with Debezium and Oracle. I'm following the next tutorial

https://github.com/debezium/debezium-examples/tree/main/tutorial

I'm using Oracle 19 local (deploy as docker)

telnet localhost 1521and respond ok

I have folder: "debezium-with-oracle-jdbc" And Dockerfile inside

I'm using Red Hat Enterprise Linux 7.9

I run as root:

export DEBEZIUM_VERSION=1.8
docker-compose -f docker-compose-oracle.yaml up --build

but I see the error

# docker-compose -f docker-compose-oracle.yaml up --build

the docker image is based on fedora-minimal, which doesn't have dnf/yum
install. If you need to install something, you have to use `microdnf` command.
However, there's no need to install libaio, it's already there:

[kafka@0a0dc118e65e ~]$ rpm -q libaio
libaio-0.3.111-11.fc34.x86_64
