Problem running getpapers on Docker

[ShweataNHegde]

Hello, I tried installing dockerised getpapers on my computer which runs Windows 10 Home OS. I was able to install docker, build an image of getpapers but I had trouble running it.
Here is all I did:

• I made the following Dockerfile:

FROM node:slim
WORKDIR /usr/src/app
RUN npm install --global getpapers

• Then built it into an image using this command

docker build -t paper_getter .

Here is what I got:

Sending build context to Docker daemon   2.56kB
Step 1/3 : FROM node:slim
 ---> 20b18b90ace4
Step 2/3 : WORKDIR /usr/src/app

SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories

• I then tried running the image using the following command.

docker run -it \
 -v $(pwd)/results:/results \
 paper_getter \
 getpapers -p -x -o /results --query 'c4 photosynthesis flaveria'

For which I got,

operable program. Check the spelling of the name, or if a path was included, verify that
the path is correct and try again.

+  ~~~~~~~~~

   ption
    + FullyQualifiedErrorId : CommandNotFoundException

• But I quickly realized that the syntax must be different for Windows. Instead, I tried this:
  docker run -it paper_getter -v results:/results
getpapers

For which I got the following error:

getpapers : The term 'getpapers' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if a path was

• I'm completely new to Docker and I can't seem to figure out where I'm going wrong. Is it because I'm building a Docker image from Windows against a non-Windows Docker host? Or, am I running wrong commands?

Can you try:-

docker run -it paper_getter -v results:/results \
getpapers -help

The first error looks like something about windows not liking the formatting of the docker run command. What is the version of docker you are using? It could be that they've changed the flag syntax at some point.

I tried what you suggested:

PS C:\Users\shweata\Dockerfile> docker run -it paper_getter -v results:/results \
>> getpapers -help
v14.10.1
getpapers : The term 'getpapers' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify

+ getpapers -help
+ ~~~~~~~~~

I get the same error again.

Can you try jamming everything onto one line? It looks like its having trouble with the linebreak. So:

docker run -it paper_getter getpapers --help

I've removed the volume mount until we get to the bottom of this

Sounds like a likely problem. Looking on the internet it seems like `^` might be the way to write multiline commands on the windows command line. See e.g. https://stackoverflow.com/questions/605686/windows-how-to-specify-multiline-command-on-command-prompt

• So I ran the following command:

docker run -it paper_getter getpapers -q viral epidemic -k 10 -o C:\users\shweata\viralepidemicstest1 -p
And this is what I got:

C:\Users\shweata>docker run -it paper_getter getpapers -q viral epidemic  -k 10 -o C:\users\shweata\viralepidemicstest1 -p

C:\Users\shweata>cd viralepidemictest1
The system cannot find the path specified.

I was able to run it but no output directory was created.

• I also tried this to see what happens:docker run -it paper_getter -v results:/results ^

getpapers -help

C:\Users\shweata>docker run -it paper_getter -v results:/results ^
More? getpapers -help
v14.10.1

So, the problem might be with mounting volumes in Windows.

[bauhuasbadguy]

In this command

docker run -it paper_getter getpapers -q viral epidemic -k 10 -o C:\users\shweata\viralepidemicstest1 -p

You are trying to use a location that exists on your windows machine that does not exist inside the docker container. When the -v flag is used it connects a folder on your local machine to a folder inside the docker container. The container will be using a unix file system so will start with a / so there won't be a C drive inside the container.

If you want to have a look inside the container you could run

docker run -it paper_getter bash

Which will make it look like you are remote sshing into a virtual machine
