Why Does My Go Web App in Docker Fail with

Docker Image Error: "standard_init_linux.go:190: exec user process caused "no such file or directory" when Running Go Web App

This error message indicates that the Docker image cannot find or execute the specified user process. The problem stems from missing dependencies or improper compilation parameters.

When building the Go web app, ensure that the webapp.go file imports the necessary packages, such as the net package. Additionally, the net import includes libc by default as a dynamically linked binary, which may be missing in the Docker image.

To resolve this issue, use the following compilation parameters:

CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -tags netgo -ldflags '-w' -o mybin *.go

By specifying CGO_ENABLED=0, you disable CGO (Go's mechanism for calling C functions) and force pure Go compilation, eliminating the need for libc. GOOS=linux and GOARCH=amd64 indicate the target platform and architecture. -a builds a statically linked binary, and -ldflags '-w' strips unnecessary information from the binary.

After recompiling with these parameters, build the Docker image, and run it. The error should now be resolved, and the web app should function correctly within the container.

The above is the detailed content of Why Does My Go Web App in Docker Fail with 'standard_init_linux.go:190: exec user process caused 'no such file or directory''?. For more information, please follow other related articles on the PHP Chinese website!

Learn Go String Manipulation: Working with the 'strings' PackageMay 09, 2025 am 12:07 AM

Go's "strings" package provides rich features to make string operation efficient and simple. 1) Use strings.Contains() to check substrings. 2) strings.Split() can be used to parse data, but it should be used with caution to avoid performance problems. 3) strings.Join() is suitable for formatting strings, but for small datasets, looping = is more efficient. 4) For large strings, it is more efficient to build strings using strings.Builder.

Go: String Manipulation with the Standard 'strings' PackageMay 09, 2025 am 12:07 AM

Go uses the "strings" package for string operations. 1) Use strings.Join function to splice strings. 2) Use the strings.Contains function to find substrings. 3) Use the strings.Replace function to replace strings. These functions are efficient and easy to use and are suitable for various string processing tasks.

Go bytes package: short reference and tipsMay 08, 2025 am 12:05 AM

Go's bytes package is mainly used to efficiently process byte slices. 1) Using bytes.Buffer can efficiently perform string splicing to avoid unnecessary memory allocation. 2) The bytes.Equal function is used to quickly compare byte slices. 3) The bytes.Index, bytes.Split and bytes.ReplaceAll functions can be used to search and manipulate byte slices, but performance issues need to be paid attention to.

Go bytes package: practical examples for byte slice manipulationMay 08, 2025 am 12:01 AM

The byte package provides a variety of functions to efficiently process byte slices. 1) Use bytes.Contains to check the byte sequence. 2) Use bytes.Split to split byte slices. 3) Replace the byte sequence bytes.Replace. 4) Use bytes.Join to connect multiple byte slices. 5) Use bytes.Buffer to build data. 6) Combined bytes.Map for error processing and data verification.
