I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.
So it might be really unintuitive at first but lambda functions have three states.
package main | |
import ( | |
"net/http" | |
"os" | |
"bytes" | |
"path" | |
"path/filepath" | |
"mime/multipart" | |
"io" |
# Example YAML configuration for the sidecar pattern. | |
# It defines a main application container which writes | |
# the current date to a log file every five seconds. | |
# The sidecar container is nginx serving that log file. | |
# (In practice, your sidecar is likely to be a log collection | |
# container that uploads to external storage.) | |
# To run: |
package main | |
import ( | |
"bytes" | |
"fmt" | |
"io" | |
"log" | |
"mime/multipart" | |
"net/http" | |
"os" |
