Go Setup

Installing Go using asdf

• This is how I manage my local Go & Python installations
• You can have a seperate instance of Go versions for each project.

1. Installing asdf using homebrew

• brew install asdf
• echo -e "\n. $(brew --prefix asdf)/libexec/asdf.sh" >> ~/.zsh_profile

2. Installing go

• asdf plugin add go
• asdf install go latest

3. Setting a Version

• asdf global go latest if you need to a set a local env.
• asdf local go latest

Running Go Files Locally an Example Project.

1. Create a Directory i.e. hello

2. Go into the dircectory cd hello

3. get the path of the directory pwd >> documents/projects/hello

OR just name it based on the directory i.e. object-storage.app

4. init the project go mod init object-storage.app

5. check the go.mod file cat go.mod

6. run go install

7. create a main.go file

add this code snippet

package main

import "fmt"

func main() {
    fmt.Println("Hello, SlimeCorp")
}

8. finally run the file go run main.go

Encoding & Decoding Base64 JSON key.

• Never commit your json service account details from GCP.
• This is just one method to get service accounts to work in Railway for GCP specfically

1. In your terminal run cat object-storage-railway.json | base64

output will be a encoded base64 string copy and use that and .ENV variable or value inside of Railway.

2. Inside the code we have a function that will decode the string at runtime to use the service account permissions.

func CovertStringToJSON(env_details string) []byte {
	decoded_json, err := base64.StdEncoding.DecodeString(env_details)
	if err != nil {
		panic(err)
	}

	return decoded_json

}

Railway Setup:

• Railway: railway.app

1. Link Git Repo to Railway
2. Add encoded base64 service account value to the variable of the railway project for this repo.
3. Add ENV=PROD in addition to the variables. This allows you to use a .env file locally if you want to test before you deploy to Railway but the beauty of Railway it can be part of your testing & ci/cd stack.
