Hi @L3AZH I'm able to reproduce the error you describe in this issue, but I think it's not caused by the library itself: in the ZIP file provided above, the Dockerfile lives in a directory with no access to the If from the cmd/httpserver dir you run I'd suggest trying a structured format that allows building the image. |

Hi @mdelapenya, I'm able to run My My package main_test
import (
"context"
"go-specs-greet/go_specs_greet"
"go-specs-greet/specifications"
"log"
"os/exec"
"testing"
"github.com/alecthomas/assert/v2"
"github.com/testcontainers/testcontainers-go"
"github.com/testcontainers/testcontainers-go/wait"
)
func TestGreeterServer(t *testing.T) {
ctx := context.Background()
cmd := exec.Command("pwd")
stdout, err := cmd.Output()
if err != nil {
log.Fatalln(err)
}
path := string(stdout)
log.Println(path)
req := testcontainers.ContainerRequest {
FromDockerfile: testcontainers.FromDockerfile{
Context: "../../.",
Dockerfile: "Dockerfile",
PrintBuildLog: true,
},
ExposedPorts: []string{"8080:8080"},
WaitingFor: wait.ForHTTP("/").WithPort("8080"),
}
log.Println(req.FromDockerfile.Context)
log.Println(req.FromDockerfile.Dockerfile)
container, err := testcontainers.GenericContainer(ctx, testcontainers.GenericContainerRequest{
ContainerRequest: req,
Started: true,
})
assert.NoError(t, err)
t.Cleanup(func() {
assert.NoError(t, container.Terminate(ctx))
})
driver := go_specs_greet.Driver{BaseURL: "http://localhost:8080"}
specifications.GreetSpecification(t, driver)

Simply downloading your ZIP file and running the tests I get this: So it seems to build the Docker image but the assertions fail. |

So I just do the same as you, |
Mmm, so it happens on a Windows machine? Let me check on that platform, but it will be next Monday 🙏 I'm reopening the issue just until we confirm it's not a Windows issue |

@L3AZH good news! We discovered a weird behaviour in how Docker handles absolute Vs relative paths when tarring string representations for paths on Windows. We have fixed it in #814, always passing the absolute path to Docker. On other hand, we had a hard time understanding the layout of the project, as it's not very common to see the Dockerfile copying files from In any case, thanks for reaching out with this issue, it helped us to trigger an internal discussion on how Docker works under the hood. Cheers! |
