Update version execution error: could not determine host context "default" does not exist

[ownicn]

Describe the bug
After upgrading from v0.21.0 to v0.23.1, executing the lazydocker command resulted in an error :
could not determine host context "default" does not exist
unable to parse docker host ''

To Reproduce

1. choco upgrade -y lazydocker （The first installation was done through 'choco install lazydocker'）
2. lazydocker --version

Desktop (please complete the following information):

• OS: Windows 10
• Lazydocker Version v0.23.1

Duplicate of #488.

The ~/.docker folder already exists in my directory, and this issue still exists.
I resolved this issue by removing the currentContext attribute from the ~/.docker/config.json file

# set the property value to an empty string
"currentContext": ""
# or remove entire attribute
- "currentContext": "default"

This solved the issue for me too! Although it never feels good to delete something without even knowing what it does 😅 .

I can remove the currentContext and lazydocker starts working again, but I have to do that every time Docker Desktop restarts.

[mark2185]

What if you set it to an empty string?

[riley-van-hengstum]

What if you set it to an empty string?

Also when I set it to an empty string.
Docker Desktop resets the currentContext back to the default value when it starts.

I seem to have two Docker contexts:

I don't know exactly what these do. I tried removing the desktop-linux context, but that also gets recreated when Docker Deskop restarts.

This is on Windows 11, Docker Desktop 4.25.0 and lazydocker 0.23.1

I've encountered the same issue, and @xyabc120's method helps me for now. Is this the only way to go?

I have the same issue - with ~/.docker/config.json having the line "currentContext": "default", lazydocker will not start.

Setting currentContext to the empty string works around the issue - but then docker-compose won't start:

Removing the currentContext completely makes both lazydocker and docker-compose work.

Interestingly, with currentContext set to the empty string, lazydocker works but does not show all docker-compose containers, and for some docker-compose containers it shows the wrong name.

[c3cris]

Same issue. Resolved by editing docker config, but that should not be the solution

[RollsChris]

same issue for me :( removing currentContext mkaes lazydocker work but then it gets its added back when restarting docker desktop.. making it unusable

[RollsChris]

weirdly if i use "docker context use default" it disappears from the config file and lazydocker works... but still restarting docker adds it back. Something has got twisted here maybe on the docker side.

Also it might be worth noting switching to desktop-linux context also works

[hiro345g]

As a temporary workaround, I was able to get it to work by specifying the DOCKER_HOST environment variable as DOCKER_HOST="unix:///var/run/docker.sock" lazydocker. (Ubuntu 22.04)

[fmanso]

Any update on this ? How would be the workaround for Windows with Docker Desktop ?

[peauc]

@fmanso would you be able to provide a ~/.docker/config.json that is problematic? I can look onto this issue

[peauc]

I have managed to reproduce this issue on Linux, fix it & draft a PR

[gsenseless]

Stil getting this error.
My problematic config.json:

{
        "auths": {},
        "credStore": "desktop",
        "currentContext": "default",
        "plugins": {
                "-x-cli-hints": {
                        "enabled": "true"
                }
        }
}

[peauc]

@gsenseless I believe this code has not yet landed on master :).

[matheustavarestrindade]

If you are having this problem on windows, i just solved with the cmd: docker context use default
