In My mac, I have rancher desktop installed. I can run docker commands from terminal without any issue.
But however, Junit test container is complaining saying Couldn't find a valid docker environment.
Can you pls help?

I have installed Docker Desktop. hello-docker works fine from my cmd, but I can't configure Docker in my GoLand IDE, I get the following error:
Cannot connect to the docker daemon at npipe:////./pipe/docker_engine. Is the docker daemon running?
Honestly, I don't know what are local path and vm path parameters, but I can't even google something relevant about these parameters.
If I ignore this error my images just don't build in the IDE. Can somebody help with that?
I checked my Docker in cmd, works fine, Docker Desktop works too. While trying to configure, Docker Desktop is launched for sure.
I have a local dev server running on Mac OS on localhost:3000
I want to be able to run testcafe tests in the docker container, pointing to the app running on the Mac host.
Test code:
fixture('<Page>')
.page(`localhost:3000/page-test`)
I've tried docker run --network="host" which should make Mac's localhost accessible, but no success.
Have also read, host.docker.internal or docker.for.mac.localhost can be used inside the container, but there is no way for me to access, modify the image settings.
Anyone has a similar use case for testcafe docker or knows how to solve this?
Thanks, Radek
You can just use host.docker.internal instead of localhost right in your test code. It does not require image settings modification. Please, keep in mind that this feature was introduced in version 18.03.0-ce and is not available in Docker Toolbox.
I'm really new to docker. I have installed docker on my windows 10 laptop.
Then I started docker service. Please refer below screenshots.
However it shows docker running icon of docker shows it is false.
This is out put I got in power shell opened as Admin mode.
Please support me to bring to docker working status.
I'm trying to run this command :
docker daemon --insecure-registry 192.168.99.100:5000
but i'm gettin ghe following error:
exec: "dockerd": executable file not found in %PATH%
I'm using win7 and docker-toolbox 1.12.2 with VM Virtual Box.
What is the problem here?
there is a way to run this command?
That is indeed what issue 27102 report:
Docker Daemon command dockerd not found on latest stable Docker for Mac and Docker Toolbox
(this is for mac but also applies on Windows)
Docker for Mac should probably print a different message, also, we may need to check if the CLI is on the same "host" as the daemon, and print a different message based on that (as running dockerd wont work if the daemon is on a remote server).
the daemon runs in a Linux virtual machine, so you do not need to (and cannot) run it manually. It is already running of the whale is in the top bar.
Conclusion: (Aug. 2021):
I'm closing this ticket, because the current behaviour is as expected.
I think this was originally opened when the docker cli still had a daemon subcommand (during the transition from a single binary to separate binaries for the cli and daemon), which is no longer the case.
The dockerd binary, which is the docker daemon, is not available for macOS (and unlikely will be), because it's a Linux binary that (on Docker Desktop for Mac) runs inside the Docker Desktop VM.
In 2022:
I'm having this exact same issue on the most recent MacOs version (Monterey, Version 12.3.1 (21E258)).
I've uninstalled Docker & reinstalled several times, if I run docker ps or docker run hello-world as paulinechi describes, I get that same error:
docker: Cannot connect to the Docker daemon at `tcp://35.215.110.128:2375`.
Is the docker daemon running?...
Answer:
Make sure you don't have a DOCKER_HOST environment variable set; from that error, it looks like either you have a DOCKER_HOST env-var, or possibly a docker context that defines a non-standard location to connect to the daemon.
The default should be to connect with the Engine API using a unix-socket (unix:///var/run/docker.sock)
Confirmation:
I forgot I was pointing to a DOCKER_HOST on a remote machine that has since shut down.
I'm trying to do something fairly non-standard, so I'm not sure how successful I'm going to be.
I've installed "Docker for Windows", and I'm able to use it fine from PowerShell.
I would like to be able to use a proper Linux environment though, so I've installed the new Ubuntu Bash prompt for Windows 10.
I've successfully built the latest Docker client in Ubuntu/Bash. However when I run "docker ps", I get:
Cannot connect to the Docker daemon. Is the Docker daemon running on this host?
I had hoped that it might just work.
Is it possible to connect to a Docker daemon running in Windows from Ubuntu/Bash?
I figured it out. It was surprisingly simple. I just had to set the following...
export DOCKER_HOST=tcp://127.0.0.1:2375
This is actually a really cool setup.
A very fast, efficient Docker engine running in a type 2 hypervisor, and a proper Ubuntu-based development environment. Nice :-)
Notice: as #BSalita mentioned in the comment, the Docker service must be running with "Expose daemon on tcp://localhost:2375 without TLS" enabled, which can be found in the general section in Docker Settings (right click on the system tray icon then "Settings..."). This option is not checked by default.
