Dockerized plastimatch container

[Paul Ehrlich]

Hello,

I am trying to install a dockerized version of plastimatch for one of our backend services. I am able to install plastimatch 1.7.0 in an Ubuntu 18.04 container. When I try to install plastimatch  on a newer image I am getting the follwing error:

 > [5/5] RUN apt-get -y install plastimatch:
#9 0.176 Reading package lists...
#9 0.546 Building dependency tree...
#9 0.621 Reading state information...
#9 0.632 Package plastimatch is not available, but is referred to by another package.
#9 0.632 This may mean that the package is missing, has been obsoleted, or
#9 0.632 is only available from another source
#9 0.632
#9 0.636 E: Package 'plastimatch' has no installation candidate

Does anyone have a clue what is meant by that? We are also running a workstation on Ubuntu 18.04 and are able to build a docker container on a newer version of Ubuntu (20.04)

Here is the Dockerfile:

FROM ubuntu:20.04
RUN apt-get -y update && apt-get -y install && apt-get -y upgrade
COPY . /app
WORKDIR /app
RUN apt-get -y install plastimatch

Thanks in advance for your help,

Paul

Hi Paul,

I know *absolutely* nothing about docker, but I am willing to try to help. Can you please explain the following?

"I am trying to install a dockerized version of plastimatch for one of our backend services. I am able to install plastimatch 1.7.0 in an Ubuntu 18.04 container. When I try to install plastimatch on a newer image..."

My parsing of this statement is that you have a dockerized plastimatch 1.7.0, and it installs on 18.04 but not 20.04. Did I get that right?

My vague idea is that docker creates a bundled executable that you can create in one platform and then run in another platform. Did I get that right? And do they also need to be installed? How do you install them?

If you can give more detailed information and/or steps to reproduce that would be helpful. Especially regarding which plastimatch version and which Ubuntu platform is failing. My (again) vague thought is that the prerequisites (e.g. dcmtk) are not available or missing in the dockerized exe.

Greg

Hi Greg, 

you are right. I was able to run plastimatch 1.7.0 in a ubuntu 18.04 container. However, if I want to upgrade the OS and plastimatch (20.04/1.8.0) it fails.

You could try to reproduce this error by creating a docker file (you also have to call it Dockerfile) with the following content: 

FROM ubuntu:$(version)

RUN apt-get -y update && apt-get -y install && apt-get -y upgrade
COPY . /app
WORKDIR /app
RUN apt-get -y install plastimatch

Make sure that docker is installed and run:

docker build -t $(container-name) $(path-to-your-dockerfile)

This step produces the error. You can run the container with:

docker run -it --rm $(container-name)

Hi Paul,

I was able to successfully follow your instructions and create the docker file. Unfortunately, I wasn't able to reproduce the problem.

$ docker build -t plm-ubuntu .

Any idea what I could be doing differently? This was on Debian Buster, Docker version 18.09.1,

Greg

Hi Greg, 

I think I found the issue. As mentioned, I found it odd that the exact Dockerfile would build perfectly on our linux server, but fail locally on my Mac. 

It is not a problem of plastimatch, but a problem of the different CPU instruction set of the new apple chips. Many libraries are also facing similar issues.

I wrote a stackoverflow post for this problem, an easy solution and also linked some useful references.
