I have a local jenkins on OSX.
It's working fine, but now I want to perform docker builds inside the jenkins.
So I have to install docker inside my jenkins.
Is this possible, because I thought you can't install docker on osx? (only docker-machine).
I don't know if it's possible to configure jenkins to use docker-machine?
Docker-machine is a Linux VM.
First option: start a Jenkins slave inside this VM, it will have access to the docker daemon to build your image.
Second option: configure Jenkins to use Docker slaves using Docker-machine. You will be able to build docker images from a docker slave.
I would do this for a PoC or an evaluation setup. For a Production setup, I would use real linux hosts to build Docker images.

Help me friends, please. I'm a noob in docker.
I'm working with laravel an create project with Docker in location.
root#VIGIA-PC:/mnt/d/projects/fastfood-app/fastfood-api#
docker was working but when I shut down my pc, and then I turn on it, the docker container is not running, why?
when I go to to the project folder and type ls no appear files from debian terminal, when I going to windows they are here.
I runned docker ps and show the follow:
Information
windows version 10
distro linux debian
build 19042
Docker version 20.10.2, build 2291f61
You'll have to change the behavior of your docker apps.
If the host is being restarted, so are the containers running on it : https://docs.docker.com/config/containers/start-containers-automatically/
I have already solved my problem.that was a problem from path
I've installed Stable Docker Desktop for WINDOWS 10. I tried running:
docker run hello-world
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
So it appears that it can connect to Docker daemon. However when I run my own command:
C:\Users\cortex>bash
DESKTOP-2GHN95P:/tmp/docker-desktop-root/mnt/host/c/Users/cortex/# cortex deploy
I get following error:
error: unable to connect to the Docker daemon
please confirm Docker is running, or if Docker is not installed, install it by following the instructions for your operating system: https://docs.docker.com/install
I'm new to Docker and I can't figure out this problem. Anyone has any ideas?
Looks like you're trying to run cortex from a WSL, which is trying to take action on the docker engine in the host OS. If you have WSL 2, you can enable the WSL 2 integration for Docker desktop in the settings. If that's not an option, you can always install docker on your WSL instead,
I want to install docker using command line not using docker for mac. I have downloaded the individual binary for Mac from this link.
docker ce binaries
I am able to run docker command but if I run docker ps then it shows
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
I tried another way to downloading docker using brew as below
brew cask install docker
But using brew it only download the desktop setup of docker and I have to start it manually.
So I am looking for a solution in which I can install and run docker through command without involving any UI.
Thanks
The error above means that the docker service is not running so you have to run it first. Then enable it to start on boot - to avoid the need to start it each time you login to your macOS - at the end you should be able to use docker cli without issues
I'm using Windows 7 Pro and have existing shared Docker engine running on a Linux. I would like to use my workstation (with development environment) to access shared Docker engine.
Does someone know how to retrieve Docker client only for Windows 7 ? I have no admin privilege, so I can't install Docker Toolbox.
Older Clients can be found here https://download.docker.com/win/static/stable/x86_64/
And here a some newer Builds by Stefan Scherer (Docker employee) https://github.com/StefanScherer/docker-cli-builder.
Just download docker.exe and add it to your windows path variable.
Then set your DOCKER_HOST variable to define against which Docker daemon you want to speak.
The official Downloads have finally been published:
Mac CLI binaries are available at
https://download.docker.com/mac/static/stable/
Windows CLI (and daemon) binaries at https://download.docker.com/win/
Linux CLI packages are available for each distro as docker-cli (deb and rpm) packages: https://download.docker.com/linux/ubuntu/dists/focal/pool/stable/amd64/

Although docker provides a REST-like API, there aren't many clients for it. A quick google turned up one on github, but ymmv. Even if you did find one, you're likely to run into the same problems involved in running docker-ce locally anyway.
There are a handful of gui clients that you could run on that engine and access with a browser, but if you are specifically after a cli you're SOL with this.
If you have an ssh client (git bash, or putty, or something), and you can arrange to run a bastion container on the engine, then you could run a container to ssh into and use that as if it's your local machine. You'd still have to scp resources onto it, but you'll eventually have to solve that problem anyway. Something like:
sudo docker container run --interactive --tty -v /var/run/docker.sock:/var/run/docker.sock image
Where 'image' is a linux image with an ssh server and appropriate keys, git, and docker installed. You could mount a local volume for persistence, or you could just keep everything in git.
I want to work on an aws machine for a kaggle competition. While working on my own pc i have Anaconda installed, pycharm.
How do i set it up on an AWS machine?
Do i need to install the tools each time i log in the AWS machine.
What is the recommended way for this cases?
I thought of running a jupyter notebook instance on the remote machine, and connect to that web page via my local machine.
What are the pitfalls to be expected?
You need to launch an EC2 instance in AWS and connect it through SSH to run your algorithms. The following link can help you further.
http://www.grant-mckinnon.com/?p=6
In these cases using Docker images helps the best in encapsulating the environment. Kaggle also uses docker to create environments for kernels. You can install Docker from here. You can pull the docker image using following command,
docker pull datmo/kaggle:python
After this, you can run containers using this image and mount necessary files in order to run the same environment.
docker run --rm -it -p 8888:8888 -v ~/.:/home/ datmo/kaggle:python 'jupyter notebook'
You can also use datmo CLI in order to easily setup environment and also version control your machine learning models.
