Docker Error: OCI runtime exec failed: exec failed: container_linux.go

I have created a docker image named ocp-install from the following dockerfile

    FROM registry.access.redhat.com/ubi8/ubi-minimal:latest

    ARG INSTALL_DIR=/root/install-dir

    ENV PATH $PATH:$INSTALL_DIR

    WORKDIR $INSTALL_DIR

    RUN microdnf update && \
        microdnf install -y yum findutils && \
        mkdir -p $INSTALL_DIR

    COPY ocp-install $INSTALL_DIR

    ENTRYPOINT ["/bin/bash", "/usr/bin/ocp-install"]

I have run the command docker run -it ocp-install create for installation.

And now i want to destroy the install using command docker exec -it <containerID> destroy , however it gives the following error

OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"destroy\": executable file not found in $PATH": unknown

short answer:

exec runs a new command, destroy is the subcommand of ocp-install, so you have to specify the whole command:

docker exec -it <containerID> -- /usr/bin/ocp-install destroy

explanation

as https://docs.docker.com/engine/reference/builder/#entrypoint describe,

Command line arguments to docker run will be appended after all elements in an exec form ENTRYPOINT

ENTRYPOINT works for docker run but not docker exec

as https://docs.docker.com/engine/reference/commandline/exec/ describe,

The docker exec command runs a new command in a running container.

When you are trying the docker exec -it <containerID> destroy command, docker tried to run the command destroy instead of appending destroy args to ocp-install
