[go-nuts] Simple Go web server that service files
I'm learning Go web server programming and have copied the following
example:
func Image(w http.ResponseWriter, r *http.Request) {
f, _ := os.Open("images/my.png")
. . .
It works fine when I'm starting the Go web server with `go run main.go &`.
I.e., the file "images/my.png" is related to where I started "go run".
However, it won't be the case when the Go web server is compiled and
started the other way.
What's the proper way to make sure it always works, including starting from
docker container?
THX!

[go-nuts] Creating Go web server into small Docker images
Hi, I'm trying to create Go web server into small Docker images. Here is my Dockerfile: # golang:latest as build-env FROM golang:latest AS build-env RUN mkdir /app ADD . /app/ WORKDIR /app RUN cd /app && GO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o myapp . # go build -o myapp FROM scratch COPY --from=build-env /app/myapp /app/images/* / EXPOSE 8080 ENTRYPOINT /myapp It uses the Docker Builder Pattern and scratch image, which is a special docker image that's empty. It builds OK, but when I run it, I'm getting: docker: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"/bin/sh\": stat /bin/sh: no such file or directory": unknown. How to fix it? Thx! -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] Re: Strange error after adding another sample code
Ah, that's 2nd condition to use tests in package with the "_test" as package, which I've forgotten. Thanks!

[go-nuts] Strange error after adding another sample code
What does the following error really means? can't load package: package ./.: found packages easygen (config.go) and easygen_test (example_execute.go) in /path/to/go-easygen/easygen cmd/easygen/flags.go:12:2: found packages easygen (config.go) and easygen_test (example_execute.go) in /path/to/src/github.com/go-easygen/easygen I'm been adding example tests to my package using the "_test" as package without any problem. However, the one I've just added, https://github.com/go-easygen/easygen/blob/master/example_execute.g0 gives me errors now. and I have no idea why. Here is how to duplicate the problem.
