I am new to using Jenkins and docker plugins. I have jenkins installed on my Mac Os. I am trying to build a project on jenkins using docker build and publish plugin as a build step.
It fails with below error
java.io.IOException: Cannot run program "docker" (in directory "***"): error=2, No such file or directory
Looks like docker is not available to jenkins user but available to root and other user on my Mac.
sudo su jenkins
bash-3.2$ docker ps
bash: docker: command not found
sudo su XXX
bash-3.2$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
bash-3.2$
Is this some permissions issue? Can you please help?
Thanks
Inspect the permissions of the docker binary:
stat $(where docker)
Check the owner and group,
in osx stuff is usually in staff group, try adding your jenkins user to that group:
sudo dseditgroup -o edit -a jenkins -t user staff

I just start learning laravel, and follow the tutorial from https://laravel.com/docs/8.x/installation "Getting started on Windows" .
I manage to install Docker Desktop and COnfigured to use WSL2 Backend.
When I run the command curl -s https://laravel.build/example-app | bash to create laravel application directory from cmd, this warning come out Docker is not running.
I run curl using command prompt. (cmd).
Update:
So, I run the command in Windows Terminal:.
PS E:\Play> curl -s https://laravel.build/example-app | bash
Here is the response I get:
cmdlet Invoke-WebRequest at command pipeline position 1
Supply values for the following parameters:
Uri:
Any Idea what to do?
Try to explicitly enable integration with your distro in Docker settings:
After that relaunch your WSL2 terminal & try again. That should help.
You can also open https://laravel.build/example-app in a browser & check what commands the script is running: and run them manually to check the output for any errors.
For those who are using Ubuntu or Debian can check this guide out on how to install and configure Docker.
sudo snap install docker
sudo usermod -aG docker $(whoami)
sudo chmod 666 /var/run/docker.sock
You need to install a linux distro, and then in Windows Terminal create a new tab for the linux distro and run the command there, not in a windows powershell tab.
Make sure that you are running curl command on your distro. Use Windows Terminal app and open a new tab as WSL2 (your distro).
sudo chmod 666 /var/run/docker.sock
I guess you are using ubuntu or debian.
chmod will do the trick here.
I've set up wsl 2:
PS C:\Users\User> wsl --list --verbose
NAME STATE VERSION
* Ubuntu-18.04 Running 2
However when attempting to create a container from wsl the following error is returned:
$ lxc launch ubuntu:18.04 test
Error: Get http://unix.socket/1.0: dial unix /var/lib/lxd/unix.socket: connect: no such file or directory
How to launch an LXD container from wsl2? From my understanding it should be possible given that wsl2 is a full linux kernel.
Adding sudo before the command works.
This needs to be done for every command of lxc/lxd.
Description
I am connected to my raspberry pi 1 ( via putty and I have already followed the steps as described here at "Building Debian Packages inside Docker Container with CMake on Ubuntu or Debian"
I have cloned the docker-deb-builder repo and build both the dockerfile-ubuntu-18.04 and
dockerfile-ubuntu-17.04.
Then, I have cloned the open62541 repo and checked out pack/1.0.
Afterwards, I have created the output folder in the docker-deb-builder folder and tried to run the
following command in the development folder:
./build -i docker-deb-builder:18.04 -o output ~/ma/development/open62541
But it fails with following error message:
pi#raspberrypi:~/ma/dockerVersion/docker-deb-builder $ sudo ./build -i docker-deb-builder:18.04 -o output ~/ma/dockerVersion/open62541
Running docker:
docker run -it -it -v /home/pi/ma/development/open62541:/source-ro:ro -v /home/pi/ma/development/docker-deb-builder/output:/output -v /home/pi/ma/development/docker-deb-builder/build-helper.sh:/build-helper.sh:ro -e USER=0 -e GROUP=0 --rm docker-deb-builder:18.04 /build-helper.sh
Unable to find image 'docker-deb-builder:18.04' locally
docker: Error response from daemon: pull access denied for docker-deb-builder, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
What I am trying to accomplish is to run a docker container (with an open62541 server running in it) on my raspberry pi.
Questions:
- How can I solve the problem described above?
- How or where can I integrate my customized open62541 server code?
Background Information / Reproduction Steps
Running the command cat /etc/os-release gives me the following information:
pi#raspberrypi:~/ma/dockerVersion/docker-deb-builder $ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"
Issue 1 - running a container by tag (but not finding it by tag)
Firstly, the error docker: Error response from daemon: pull access denied for docker-deb-builder occurs when you docker run using a image name that cannot be found locally, so it goes off and tries to find docker-deb-builder on hub.docker.com (publicly) and if you go look there are none with that exact name.
The error is basically telling you;
I couldn't find docker-deb-builder locally
I couldn't find docker-deb-builder on hub.docker.com (public)
I want to try hub.docker.com (private) but you are not logged in
So you might first try to build the container and docker tag it with docker-deb-builder so you can then find it locally with the command you provided in this issue.
Issue 2 - building on armv7 (raspberry pi)
The page you linked to has instructions for;
git clone https://github.com/tsaarni/docker-deb-builder.git
Looking at tsaarni/docker-deb-builder on github for the 18.04 image you're targetting i found the Docekrfile and it is using ubuntu:18.04 and you will need to modify this to use ubuntu:18.04#sha256:60a99a670b980963e4a9d882f631cba5d26ba5d14ccba2aa82a4e1f4d084fb1f which is the signature for the armv7.
Might just add, to make sure in case you're not aware, to run on armv7 you must also docker build it on armv7
I have Docker Toolbox installed on my local machine and I'm trying to run Ruby commands to perform database migrations. I am using the following docker commands within the Docker Toolbox Quickstart Terminal Command Line:
docker-compose run app /usr/local/bin/bundle exec rake db:migrate
docker-compose run app bundle exec rake db:create RAILS_ENV=production
docker-compose run app /usr/local/bin/bundle exec rake db:seed
However, after these commands are called, I get the following error:
Could not locate Gemfile or .bundle/ directory
Within Docker Toolbox, I am within my project's directory as I run these commands (C:\project).
After doing some research, it appears that I need to mount my Host directory somewhere inside my Home directory.
So I tried using the following Docker Mount commands:
docker run --mount /var/www/docker_example/config/containers/app.sh:/usr/local/bin
docker run --mount /var/www/docker_example/config/containers/app.sh:/c/project
Both of these commands are giving me the following error:
invalid argument "/var/www/docker_example/config/containers/app.sh:/usr/local/bin" for --mount: invalid field '/var/www/docker_example/config/containers/app.sh:/usr/local/bin' must be a key=value pair
See 'docker run --help'
Here is what I have in my docker-compose.yml file:
docker-compose.yml:
app:
build: .
command: /var/www/docker_example/config/containers/app.sh
volumes:
- C:\project:/var/www/docker_example
expose:
- "3000"
- "9312"
links:
- db
tty: true
Any help would be greatly appreciated!
The issue is because you are running on windows. You need a shared folder between your Docker machine and the Host machine.
Above is on my mac. You can see my /Users is shared as /Users inside the VM. Which means when I do
docker run -v ~/test:/test ...
It will share /Users/tarun.lalwani/test inside the VM to /test inside the container. Now since /Users inside the VM is shared to my host this would work perfectly. But if I do
docker run -v /test:/test ...
Then even if I have /test on my mac it won't be shared. Because the host mount path is dependent on the Docker host server.
So in your case you should check which folder is shared and then to what path is it shared. Assuming C:\ is shared at /c Then you would use below to get your files inside the VM
docker run -v /c/Project:/var/www/html ..
I'm running Docker on Windows ("Docker Toolbox", not "Docker for Windows").
I've built an image with a rails app inside. It works properly on my Mac OS but stucks on production on Windows.
Using Docker 1.12 and docker-machine 0.8.0 on both machines.
When I create a machine and try to run the container from image, I do:
docker run -it myRepo:myTag bash
which opens me a interactive terminal on Mac OS, but Windows 7 and Windows Server 2011 are both responding with:
"Error response from daemon: oci runtime error: exec: "bash":
executable file not found in $PATH."
I use the MINGW64 shell via the Docker Quickstart Terminal but the old cmd.exe returns the same.
Can anybody help me with this issue? I've tried several hours to find a solution but there are too few answers for Windows.
Thank you in advance!
I also use Windows 7 with MINGW64. Here is what I get using nginx as example:
$docker run -it nginx bash
cannot enable tty mode on non tty input
I don't think you can open a tty using MINGW64.
You can try:
$docker run -i nginx bash
ls
bin
...
You will so no prompt or any indication you are inside the container. Just run ls and it should work inside your container.
Another option is to try to use winpty for the tty:
$ winpty docker run -it myRepo:myTag bash
root#644f59e6f818:/#
Have you tried?
$ winpty docker run -it myRepo:myTag /bin/bash
I haven't got the problem you are mentioning but I have seen it before when I was mapping volumes.
If you are mapping volumes using MINGW64, you will need to add an extra / before the local mapping. For example:
docker run -p 8080:80 -v "/$PWD":/var/share/nginx/html nginx
Let me know your findings.
