This assumes you have installed Docker on LinuxDocker is running, and that you have initialized swarm. Let's say you have an application named "foo" built to run on docker at /tmp/foo on your Linux server running Docker. This assumes that the foo application contains Dockerfile, like this.

/tmp/foo/Dockerfile

 

And Dockerfile might contain markup like this.

FROM node:6.11.5

WORKDIR /usr/src/foo
COPY foo.json .
RUN npm install
COPY . .

CMD [ "npm", "start" ]

 

Move into the directory that contains the app.

cd /tmp/foo

 

The docker image build command is used to create an image for the application.

docker image build -t foo:1.0 .

 

If all goes well, something like this should be displayed.
