@idcristi Is this error reproducible? If so, could you provide repro steps?

[ShadowRanger]

I can confirm that I am having this same issue, however am not sure how to reproduce it exactly.

[idcristi]

The problem was when I wanted to build an image in VS Code Docker Images: Build Image and then try to run the image it appeared the error mentioned above.

In my case, the issue was solved, I downloaded the last version of VS Code 1.41 November Edition and I don't have this problem anymore.

Same issue here. No output at all, but the report says:

Action: vscode-docker.images.build

@FokkeZB Can you provide more context? Was a folder/workspace open in VS Code? Was the command invoked from the command palette or the right-click context menu? Did the folder/workspace have a Dockerfile present? Are any docker-build tasks present in tasks.json or the workspace file?

[FokkeZB]

Sure!

This happened when I followed @burkeholland's https://frontendmasters.com/courses/customize-vs-code/dockerizing-an-application/ which uses the workspace https://github.com/burkeholland/workshop-vs-code-can-do-that/blob/master/exercise-5-docker/open-me.code-workspace and project https://github.com/burkeholland/workshop-vs-code-can-do-that/tree/master/exercise-5-docker/solution.

I invoked the command from the command palette, but also tried the context menu.

There's no tasks.json and the workspace file doesn't have tasks either.

I don't know this could help or not but I've got same experience as @FokkeZB (on same repository and command palette ), I tried to use right-click and "Build Image..." then after selecting the workspace I saw this in terminal: docker build --rm -f "ckerfile" -t solution:latest "." which missed the Do on ckerfile

[mojtabast]

@philliphoff here is tasks part on workspace file:

"tasks": {
    "tasks": [
      {
        "type": "docker-build",
        "label": "docker-build",
        "platform": "node",
        "dockerBuild": {
          "dockerfile": "${workspaceFolder}/Dockerfile",
          "context": "${workspaceFolder}"
        }
      },
      {
        "type": "docker-run",
        "label": "docker-run: release",
        "dependsOn": ["docker-build"],
        "platform": "node"
      },
      {
        "type": "docker-run",
        "label": "docker-run: debug",
        "dependsOn": ["docker-build"],
        "dockerRun": {
          "env": {
            "DEBUG": "*",
            "NODE_ENV": "development"
          }
        },
        "node": {
          "enableDebugging": true
        }
      }
    ]
  },

Edit: I deleted this from the workspace file and it works fine again.

[ShadowRanger]

@philliphoff I can confirm that deleting the tasks from my workspace file as @mojtabast did the issue seems to have resolved.

I'm thinking this issue may be due to the task in the workspace file passing ${workspaceFolder} as the dockerfile and context, rather than the directory that the task is actually being executed in, such as a sub directory of the main project? Maybe ${fileDirname} or something needs to be used instead?

[ShadowRanger]

@philliphoff I can confirm that replacing ${workspaceFolder} with ${fileDirname} in the task definitions resolved the issue for me. Hopefully this helps with releasing a fix for the issue.

hello, i have same problem on docker:build but i don´t have the workspace file on my folder:

hello, i have same problem on docker:build but i don´t have the workspace file on my folder:

For information, I generate the file for workspace on menu File -> Save Workspace As. Then I Open it e delete tasks like described on comment https://github.com/microsoft/vscode-docker/issues/1462#issuecomment-567510258. It worked.

[bwateratmsft]

I think this is fixed by #1639. I will investigate in the morning and confirm; if so will close this issue.

[bwateratmsft]

Yes, it looks like this is the same issue as those fixed by #1639. All of the reports here involve workspaces, where we know things were going wrong. #1639 ensures we only ever scaffold workspace folder tasks.

[bwateratmsft]

A fix for this has been released.
