Unable to deploy golang app to Azure app services container

Question

I've tried a lot of Dockerfile samples to build my golang app, they're working fine running on local.

Here is the last one Dockerfile I tried

FROM golang:alpine
EXPOSE 80
RUN  mkdir -p /app
WORKDIR /app
COPY . .
RUN go mod download
RUN go build -o app
ENTRYPOINT ["./app"]

I push my image to my Azure Container registry and use it via App service(linux) Deployment Center.

errors I got:

You can try to solve your problem in the following two ways.

1. According to your screenshot, you can add a startup command to the dockerfile.

   2. Changing RUN to CMD stops the container from working

2. Make sure your files have been posted to the scm website. After under wwwroot, use the startup command to start your application.

    go run main.go

Answer 2

I modified the port listening to 80 (App service default WEBSITE_PORT)

add ENV to Dockerfile

ENV GOOS=linux GOARCH=amd64

Change Entrypoint

ENTRYPOINT [/app/app]

finally works.
