I'm unable to run the eclipse/che local image. i.e., from the eclipse/che source code in my pc.

Here are the steps that i tried:

1. Clone the eclipse/che src code into //d/checmd3/che.

git clone https://github.com/eclipse/che.git &
git checkout tags/7.0.0-beta-2.0

2. Build it
   cd assembly/assembly-main
   mvn clean install

...A new assembly is placed in:

cd che/assembly/assembly-main/target/eclipse-che-/eclipse-che-

3. Run it in docker

docker run -it --rm -v //var/run/docker.sock://var/run/docker.sock -v //d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0
:/che -e CHE_ASSEMBLY=//d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0 -v //d/checmd3/che/tmp:/data eclipse/che start

After step #3 above, the following message was shown:
Unable to find image 'eclipse/che:7.0.0-beta-2.0' locally
7.0.0-beta-2.0: Pulling from eclipse/che

I believe that docker is not trying to run the image from my local pc ?
I'm not sure if step #3 above is the issue or not. Please help me in running the image from the src code cloned in my pc.

I'm unfamiliar with Eclipse Che but, it appears you can simply run their image(s) on your machine assuming that you've Docker installed.

Start by creating a local data directory, perhaps:

mkdir -p $PWD/che/data

Then:

docker run 
--interactive 
--tty 
--rm 
--net=host 
--volume=/var/run/docker.sock:/var/run/docker.sock 
--volume=$PWD/che/data:/data 
eclipse/che:nightly start

https://www.eclipse.org/che/docs/che-6/docker-single-user.html

You may not need the --net=host flag

You should then be able to then access the tool:

http://localhost:8080

NB
Your steps 1&2 (git clone... and mvn clean install) are probably redundant. These are likely the commands to build the Docker image. But, since the image already exists in dockerhub, you need not follow these steps.

Try this docker command:

docker run -it --rm 
-v /var/run/docker.sock:/var/run/docker.sock 
-v /d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0:/che 
-e CHE_ASSEMBLY='/d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0' 
-v /d/checmd3/che/tmp:/data 
eclipse/che start

ABOVE COMMAND IS WORKING

Thank you. I tried the following docker command:

docker run -it --rm -v //var/run/docker.sock://var/run/docker.sock -v //d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0
:/che -e CHE_ASSEMBLY='//d/checmd3/che/assembly/assembly-main/target/eclipse-che-7.0.0-beta-2.0/eclipse-che-7.0.0-beta-2.0' -v //d/checmd3/che/tmp:/data eclipse/che start

but, still the message shown is:

Unable to find image 'eclipse/che:latest' locally

latest: Pulling from eclipse/che

(docker is still not using the source code built locally in my pc)

If you want to run your custom Che binaries, the syntax you use is the correct one. Che CLI will pull default image anyway, but your binaries will be mounted into a container. Will that work for you?

If you want to run your own image for some reason, you may simply pass the following env to CLI.

-e IMAGE_CHE=myRegistry/myRepo:myTag

You could try first to prevent Eclipse Che from pulling the image from the Docker hub by setting: CHE_DOCKER_ALWAYS__PULL__IMAGE=false in your che.env config file.

If it doesn't help then I think you need to install and run a local Docker registry, then push your Eclipse Che image that you have built locally to that registry.

docker run -d -p 5000:5000 --name registry registry:2
docker image tag che:7.0.0-beta-2.0 eclipse/che:7.0.0-beta-2.0
docker push eclipse/che:7.0.0-beta-2.0

Then you can pull and run your image using your Docker run command.

You can stop the registry by:

docker container stop registry && docker container rm -v registry

There was an error when i ran the command you suggested:

$ docker run --interactive --tty --rm --net=host --volume=//var/run/docker.sock://var/run/docker.sock --volume=/$PWD/che/data:/data eclipse/che:nightly start

The following is the log:
