I am trying to build an image with docker and then upload it to the docker hub, after passing the quality tests I receive the following error: docker: not found, how can I communicate my docker service (localhost) with the container of jenkins.
Important: I have docker desktop installed locally and I have installed jenkins in a local container also in windows 10 pro.

You have 2 options to do this:
Install Docker inside your Jenkins Container and also add a bind mount for the Docker socket from your host. Otherwise your Docker Daemon inside your Container wont work. On Linux this socket is /var/run/docker.sock, so the bind mount would look like -v /var/run/docker.sock:/var/run/docker.sock.
Use a different slave agent for the Building Image Stage where you have docker installed. For e.g. you could use Docker-in-Docker (https://hub.docker.com/_/docker) as a Slave Agent for Jenkins (connected via ssh) and run your docker build inside this slave agent.

Objective:
I have 200+ projects using docker builds they run docker in their own docker daemon.To reduce cost i setup a central docker build server where i have to allow all projects to build docker images securely
Description
I created the setup with jenkins docker pipeline by installing docker plugin in jenkins and connected to my docker host via docker API.when i run build it launch docker host as jenkins slave container and allow to run docker build
Issue
Setup works fine for building docker image but my concern is with security
how to securely allow 200+ projects to connect docker daemon?
How to restrict access of each users based on roles?
How to forbidden docker run command in docker daemon? they are restricted to run docker run
Platform i use:
Jenkins running in redhatopenshift
docker host in a linux box
Can any suggest me the steps to fix this security hole

I have docker installed on my Windows 10 OS on my laptop. Also I have pulled the jenkins image and created a container out of it (Image: docker pull jenkins/jenkins:latest).
My jenkins is up and running on localhost:8080. Now I have installed Docker plugin within the Jenkins and then I Add a new Cloud to run my build against docker.
However, while giving the docker host URI as "tcp://localhost:2375" it is giving me Connection Refused
Debug Steps:
I have already made by docker server listening on port 2375
I tried adding the host entry in C:\ProgramFiles\Docker\config\daemon.json
I tried adding an env variable DOCKER_HOST to "tcp://localhost:2375
But none of the above worked.
However, when I launch jenkins on my local windows machine instead of launching it from docker, it is able to resolve the Docker host URI.
I've got build agent machine on Amazon Linux AMI. It has docker container jetbrains/teamcity-agent:latest. I can see build agent in TeamCity panel.
When I'm trying to run build with docker build/push commands I'm getting this error
Cannot login to registry docker.io (new); cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?; exit code 1 (Step: docker build (Docker))
What's wrong with teamcity-agent?
I guess that the jetbrains/teamcity-agent:latest will be running as a user that does not have docker permissions. Either the user that runs the commands in this image needs to be added to the group docker, or via ACLs be given permission to the docker socket /var/run/docker.sock. Note that this is root-equivalent.
I have a jenkins single instance running in a docker container. The host is AWS 16.04.3 LTS (Xenial Xerus) system. I want the jenkins run my build inside a docker container but since jenkins is already running inside a docker. I don't want a nested docker container running in the build. How can I make jenkins launch a docker container on the host instead of itself container?
I found a solution for that is to mount this directory on jenkins container:
docker run -v /var/run/docker.sock:/var/run/docker.sock
I want to use the docker command line tool as in "docker ps", "docker build" and "docker run". How can I connect "docker" to the Docker Daemon inside the CDK, so I can create RHEL-based Docker images?
Use the vagrant-service-manager plugin to set up your host environment for connecting your client Docker binary (docker) to the Docker service running inside CDK. In the directory with the Vagrantfile you used to launch CDK, run:
eval "$(vagrant service-manager env docker)"
This will export environment variables that instruct the docker binary to connect to CDK.
To display info about the services running inside CDK and about the necessary settings to connect to the from your host (i.e. to see what the first command does), run:
vagrant service-manager env
See documentation for details: Using the vagrant-service-manager Plugin.
If you don't already have the docker client binary installed on your host system, vagrant-service-manager can do it for you:
vagrant service-manager install-cli docker
More details in documentation: Preparing Host System for Using Docker from the Command Line.
Just like using the docker binary to connect to the Docker daemon inside CDK, you can use the oc binary to connect to the OpenShift service running in CDK. Installation and set up is analogous to the docker client.
