Flexera Kubernetes Agent - Docker File (Creation)

[davidle]

We are in the onboarding stages for deploying the Flexera Kubernetes Agent in our AKS environment. 

Before we can publish the docker image (flexera-krm-x.y.z.tar) into our internal registry (ACR), our Platform DevOps Team has insisted that we create a Docker File that contains a list of instructions to be executed in sequence to build an image:

# Define base image

FROM ubuntu:16.04

 

ENV LANG='en_US.UTF-8' LANGUAGE='en_US:en' LC_ALL='en_US.UTF-8'

 

# Adding Group and User

RUN groupadd --gid 1000 platform \

  && useradd --uid 1000 --gid platform --shell /bin/bash --create-home platform

 

# Download and install dependency

----

 

# Tell image what to do when it starts as a container

----

 

Is this request even possible? Please forgive me if the context does not make sense, as I am still trying to wrap my head around this necessary process from the team.

Hi @davidle

It shouldn't be necessary to create a Dockerfile to build a container image. The image is provided to you already completely built, as a tar archive that was exported using the "docker save" command. It can then be imported back into Docker using the "docker load" command, and then pushed to the registry as-is.

Perhaps the DevOps team is under the misapprehension that the tar archive is not itself a complete image and therefore has to be populated into container image prior to being pushed to the registry?

@Colvin - Thanks for your reply. 

DevOps team was under the misapprehension that the tar archive is not a complete image.

I provided your reply and they allowed us to move forward with publishing the krm agent into our internal ACR.

Is there a documented process to run a kubernetes agent in AKS, GKS, etc?  We are looking for something to get this done.  Any help is appreciated.  Thank you

Did you check the instructions outlined in Two FlexNet Kubernetes Agents already?

Thanks,
