Closed mavogel closed 3 years ago
I fixed this. And usually I leave a comment when I do. Really disappointed that I didn't though because now I don't remember how I did. xD
I think what happened was I misunderstood how Docker is meant to be used from within WSL 2. I installed it in the Linux distro. I didn't use Docker Desktop in Windows (which makes Docker available for use from within WSL 2 as long as Windows programs are on the path - which is the default setting for WSL 2).
And I think when I used the installation of Docker that was done from the host side in Windows 10 using Docker Desktop, it worked.
What a pity. If you find out/remember the steps how to fix it, then please update here and we'll add it to the documentation.
@mavogel Once I typed it all out, I remembered it. That's exactly what it was. I would consider this issue closed. As far as I know, it's just an issue with how I was using Docker, which of course let to an issue with this provider trying to use Docker.
Alright, thanks for the update.
Hi there, sorry for barging in after this one was closed but I can't seem to figure out a solution to this issue.
I started from here which was the exact problem I had: https://github.com/hashicorp/terraform-provider-docker/issues/180
But I see that that repo is closed now, for some reason. The solution suggested there, is not working as of today on a fresh installation of terraform and docker. So I decided to try the docker port open instead, even if it's a security issue. I'm just testing locally after all, no big deal.
If you think that there will be a better place to post this, please link it for me.
I'm following this tutorial: https://learn.hashicorp.com/tutorials/terraform/install-cli?in=terraform/gcp-get-started And I altered my main.tf file to this:
terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = "~> 2.7"
}
}
}
provider "docker" {
# host = "npipe:////.//pipe//docker_engine"
host = "tcp://127.0.0.1:2375/"
}
resource "docker_image" "nginx" {
name = "nginx:latest"
keep_locally = false
}
resource "docker_container" "nginx" {
image = docker_image.nginx.latest
name = "tutorial"
ports {
internal = 80
external = 8000
}
}
Despite that, it output an error:
╷
│ Error: Error pinging Docker server: Cannot connect to the Docker daemon at tcp://127.0.0.1:2375/. Is the docker daemon running?
│
│ with provider["registry.terraform.io/kreuzwerker/docker"],
│ on main.tf line 10, in provider "docker":
│ 10: provider "docker" {
│
╵
Even if I have the ports open and the docker engine running. I have docker installed and running from the windows host and I already use it successfully while creating images/containers directly with the docker
and docker compose
commands from inside the WSL distro (ubuntu 20.x in my case).
Hi @theCrius , no worries. We're happy to help. Could you update to the latest version ~> 2.13.0
and try again?
Unfortunately, I don't have a windows machine to test here yet (it's in progress)
Hey, thanks for the quick reply.
When running terraform init
I get this ouput:
Initializing provider plugins...
- Reusing previous version of kreuzwerker/docker from the dependency lock file
- Using previously-installed kreuzwerker/docker v2.13.0
However, I checked the "show terminal" button on the tutorial I was following and noticed that in the sandbox, the commands are working. So I checked the main.tf
files in there and noticed that it's different from the one written in the tutorial itself.
The main.tf
file that the sandbox terminal uses is:
terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
}
}
required_version = ">= 0.13"
}
resource "docker_image" "nginx" {
name = "nginx:latest"
}
resource "docker_container" "nginx" {
image = docker_image.nginx.latest
name = "tutorial"
ports {
internal = 80
external = 80
}
}
So I tried starting from that one and making just some small changes. ports -> external
set to 8000
. Not specifying a version for kreuzwerker/docker
is downloading already the latest version (I suppose) but just in case I added that as well.
The final version of the file is this one:
terraform {
required_providers {
docker = {
source = "kreuzwerker/docker"
version = "2.13.0"
}
}
required_version = ">= 0.13"
}
resource "docker_image" "nginx" {
name = "nginx:latest"
}
resource "docker_container" "nginx" {
image = docker_image.nginx.latest
name = "tutorial"
ports {
internal = 80
external = 8000
}
}
I cleaned up everything except the main.tf
file and run again terraform init
and terraform apply
and it works without a fuss.
I also tested by removing the option Expose daemon on tcp://localhost:2375 without TLS
from Docker Engine and again, cleaning everything and running again init
and apply
and it works flawlessly.
I guess the problem was this snippet:
provider "docker" {
host = "npipe:////.//pipe//docker_engine"
}
# But why it was there and it's a problem, I don't know.
Is there a way to reach the writers of the tutorial to tell them to update the content? I can do it myself If it's an open source project as well.
@theCrius I asked internally what's the best way to update this page and will come back to you :) THanks for reporting this. I'm also interested in having the tutorials work
Good to know @mavogel, let me know if I can help in any way. My office's laptop run on windows so I can run tests if needed.
My experience with Terraform is not vast but I'm quite experienced with devops works anyway (dockers, kubernetes, jenkins, etc) so, as much as I can, I'll gladly help.
@theCrius , here the internal response:
I'm being told the feedback link at the bottom of the tutorial is the best place to report this, but also that the Learn team is aware of the issue and is working on it.
Thanks for reporting the issue, and if you feel contributing to this project let me know :)
Thanks @mavogel, I had already wrote a feedback specifying the issue the other day. I guessed that that could have been one of the channels anyway :)
Have a good weekend!
I replied in the feedback as well. I just removed
provider "docker" { host = "npipe:////.//pipe//docker_engine" }
and it worked for me
I had a problem with the lab and found this thread. Every time problem was with this part
provider "docker" {
host = "npipe:////.//pipe//docker_engine"
}
I ran docker from Win start menu and after terraform apply I got the error docker
Error: Error initializing Docker client: protocol not available │ │ with provider["registry.terraform.io/kreuzwerker/docker"], │ on main.tf line 10, in provider "docker": │ 10: provider "docker" {}
Then I start docker with docker run -d -p 80:80 docker/getting-started and after that the protocol became available.
The part that docker has be to running is missed in the description of the lab.
I replied in the feedback as well. I just removed
provider "docker" { host = "npipe:////.//pipe//docker_engine" }
and it worked for me
This worked for me as well!
Hey all, hoping someone can try help. I am having a similar issue with my docker provider not working via Terraform Cloud.
I have been able to get this working locally but when I tried Terraform Cloud (in order to setup GitHub actions) I am now getting errors.
I am not using GCP and trying to push to docker registry instead, unsure if that matters.
I am using v3.0.1 of the plug-in. I am using debian as my WSL2 distro
I have tried to check tcp://localhost without TLS and I have tried to set the host explicitly with no luck.
Terraform v1.4.0
on linux_amd64
Initializing plugins and modules...
Planning failed. Terraform encountered an error while generating this plan.

same here, windows 11 using WSL. The problem is, that "http://127.0.0.1:2375/_ping" is not reachable from windows but in the WSL. Not sure if it is a terraform issue in itself.
But docker info
works from windows and also all other commands concerning docker; so I am not sure if maybe the plugin has an issue; including the VS Code docker integration.

make sure that the docker is running (use docker ps) before terraform apply. .
Reconfiguring docker in WSL2 to listen on port 2375 worked for me: https://stackoverflow.com/a/63417004/4479786
This issue was originally opened by @mattwelke as https://github.com/hashicorp/terraform-provider-docker/issues/303. It was migrated here as a result of the community provider takeover from @kreuzwerker. The original body of the issue is below.
Terraform Version
Terraform v0.12.29 (using old version intentionally because I'm following a tutorial that references particular modules that don't yet support 0.13)

Expected Behavior
A docker container being created.
Actual Behavior
An error applying Terraform config when it tried to use the Docker provider.
Steps to Reproduce
docker ps
)terraform apply
Important Factoids
I ensured I had Docker set up to be useable from within WSL 2 first. I was able to run commands like
docker ps
:But then, when running
terraform apply
, it displayed that error, saying it couldn't reach the daemon. I tried using the port2376
instead of2375
in the Terraform config, but that didn't work. I also tried enabling this option in Docker Desktop in Windows:But this also made no difference (even when using port
2375
in the Terraform config).I'm using Ubuntu 20.10 in WSL 2.
