How to create image with my new jar file in Docker?

问题

I'm very new to docker and need to deploy jar file into docker. So I have implemented "Hellow World" program and trying to create container as follows but I'm getting "curl: (56) Recv failure: Connection reset by peer" error while calling it.

Help me please I have been working on this for 4 days.

Dockerfile:

##### Version: 0.0.1
FROM ubuntu:14.04

MAINTAINER Siva "siva@example.com"

RUN apt-get update
#### installing JDK

RUN apt-get install -y openjdk-7-jdk

ADD dockertest.jar /usr/share/java/

EXPOSE 8089

Build command:

sudo docker build -t="img33/img33" .

Launching the container from image:

sudo docker run -it -p 80 --name imgcon33 img33/img33

For reference

docker@boot2docker:~/jardeploy$ sudo docker build -t="img33/img33" .

Successfully built f602b747548a

docker@boot2docker:~/jardeploy$ sudo docker run -it -p 80 --name imgcon33 img33/img33

docker@boot2docker:~/jardeploy$ docker ps -l

You did not define port for incomming connections, and boot2docker maps port 80 to the first free high-range port in range 49153 to 65535 (see how to do it in boot2docker and docker).

Here is the setup that worked for me (on Windows, though, but the same thing is for OSX), I have mapped your application on port 8000, please feel free to change it:

c:\>boot2docker init
Virtual machine boot2docker-vm already exists
c:\>boot2docker up
Waiting for VM and Docker daemon to start...
..........ooo
Started.
Writing C:\Users\xyz\.boot2docker\certs\boot2docker-vm\ca.pem
Writing C:\Users\xyz\.boot2docker\certs\boot2docker-vm\cert.pem
Writing C:\Users\xyz\.boot2docker\certs\boot2docker-vm\key.pem
Docker client does not run on Windows for now. Please use
    "boot2docker.exe" ssh
to SSH into the VM instead.
c:\>boot2docker ssh -L 0.0.0.0:8000:localhost:8000

Boot2Docker version 1.3.2, build master : 495c19a - Mon Nov 24 20:40:58 UTC 2014
Docker version 1.3.2, build 39fa2fa
docker@boot2docker:~$ docker run -it -p 0.0.0.0:8000:80 --name imgcon33 img33/img33

This setup maps your application like this: imgcon33 (port 80) -> docker (8000) -> boot2docker (8000) -> localhost (8000)

If you run curl from boot2docker, then a simple

curl localhost:80

should be enough. But if you want to access your application from host container (the one that hosts boot2docker), you have to run it as

curl localhost:8000
