How to import docker image from local machine into plesk

Question

I have small API app written in node.js and i want to run in docker on plesk. I successfully create image and run in container on local docker machine. I have Plesk Onyx 17.5.3 with docker extension in version: 1.3.1-126. And now I`m not sure how to run this my image run in plesk.

I tried:

1) With command docker save -o output-path image-name export image to .tar file. 2) This .tar file upload on plesk to docker extension. 3) After upload create image name "sha256:038a9". BTW: My name of docker image is wapi. 4) And if i use "Run (local)" so i can`t set port mapping. After click on OK button show Error: {"message":"No command specified"}

Can you somebody help me, please?

PS: If you want see anything (dockerfile etc.) so write it. :)

dockerfile

FROM node:7
WORKDIR /app
COPY package-lock.json .
COPY package.json .
RUN npm install
COPY /dist .
CMD npm run docker_start

yes can you show dockerfile? – Inarticulate

@sanathmeti done. But i say, application is running ok on local docker. – Loch

FYI: You can`t set port mapping because automatic port mapping is checked in your picture. – Demetrius

@Demetrius Yes, i know, but if i uncheck, so nothing happened. This is i mean. – Loch

I have exactly the same problem. Sadly there seems to be no solution to this? We can also not use Dockerhub (especially public one!). – Duyne

Answer 1

Plesk Docker Workaround: Upload your Docker-Image with FTP. Than use a shell and run the command "docker load -i [yourimagefile.tar]" to deploy the image in the repository of the PLESK-Server. After this you can use your image under PLESK without pain;)

Answer 2

That because docker image is been loosing the CMD or ENTRYPOINT metadata information while doing

docker export 

docker import

Its been discussed here

https://github.com/moby/moby/issues/8334

You can publish your image to dockerhub ( private/public ) then import that in plesk.

Thanks for your answer, but "docker export" export a container’s filesystem, not image. via: docs.docker.com/engine/reference/commandline/export – Loch

I used "docker save" to export image from local. – Loch

BTW i used export, but it is the same! – Loch

yes in that process it skipped the CMD / ENTRYPOINT metadata, you can have try with dockerhub – Inarticulate

we need a solution without dockerhub – Beckford

Answer 3

There are few ways to export/import containers and images.

Export container

docker export container-name | gzip > Zip_File_Name.gz

Import container

zcat Zip_File_Name.gz | docker import - container-name

Docker save container/image in zip file

docker save -o Zip_File_Name.tar container_name

Docker load image from zip file

docker load -i Zip_File_Name.tar
