Error response from daemon: client is newer than server (client API version: 1.23, server API version: 1.22)

Docker container requires newer version of Docker daemon than described at Prereq

Make sure your OS distribution has a kernel that supports Docker 1.8.

Reproduction Steps:

1. Run docker run same as description on Usage: Docker

Expected behavior:

The container runs.

Observed behavior:

che.sh failed with this message.

@monaka this error is caused by difference in versions of Docker in Che base image and your local Docker. Solution - either downgrade Docker in Che container or upgrade Docker on your CoreOS instance. I think option #2 is easier.

[monaka]

Yes. I know the reason why this issue is caused. There have an inconsistent requirement between the official document (>=1.8) and the official docker image (== latest). It's a point for me.

IMO,the better way is to fix description in install-pre-req or to add the special notice about the version requirement for official Docker images.
Users can figure out easier if it was documented.

@monaka Those requirements are to run Che as a server. Indeed, running it as a Docker container may cause such issues with host and container Docker versions incompatibility. I'll add some notes to docs.

@monaka you may try the new installer https://eclipse-che.readme.io/docs/usage-docker-launcher?

[TylerJewell]

@monaka - we look forward to your feedback on the new installer. One of the things this does is to launch Che from within a container. So it lets us standardize the client that is invoking Che into a container that works the same on everyone's computer. So this issue should go away. We are still making some improvements, but it is largely stabilized now.

@eivantsov @TylerJewell , I checked your new installer. My first impression is 👍 🍣.
It runs on my CoreOS 1010.6.0 (MoreOS).

Thanks for the feedback!
