I'm new to learning how to use goLang to build microservices. I had a whole project up and running locally, but when I tried deploying it I ran into a problem. The session I was working with (mgo.Dial("localhost")) was no longer working. When I put this into a docker image, it failed to connect to the local host, which makes sense, since the docker image builds it over a new OS (alpine in my case). I was wondering what I should do to get it to connect.
To be clear, when I was researching this, most people wanted to connect to a mongoDB session that is a docker container, I want to connect to a mongoDB session from within a docker container. Also once I'm ready for deployment I'll be using StatefulSet with kubernetes if that changes anything.
For example, this is what I want my program to be like:
sess, err := mgo.Dial("localhost") //or whatever
if err != nil {
fmt.Println("failed to connect")
else {
fmt.Println("connected")
What I tried doing: Dockerfile:
FROM alpine:3.6
COPY /build/app /bin/
EXPOSE 8080
ENTRYPOINT ["/bin/app"]
In terminal:
docker build -t hell:4 .
docker run -d -p 8080:8080 hell:4
And as you can expect, it says not connected. Also the port mapping is for the rest of the project, not this part.
Thanks for your help!
