certainly! in this tutorial, we will build a simple full-stack rest api using typescript for the frontend and go for the backend. we'll then containerize both parts using docker.

overview

1. **frontend**: a simple typescript application using express.
2. **backend**: a go application that will serve our rest api.
3. **docker**: containerizing both applications.

prerequisites

basic understanding of typescript, go, and docker
docker installed on your machine

step 1: setting up the project structure

create a directory for your project:

```bash
mkdir fullstack-docker-example
cd fullstack-docker-example
mkdir frontend backend
```

step 2: setting up the backend (go)

1. *initialize a go module*

navigate to the `backend` directory and create a new go module.

```bash
cd backend
go mod init backend
```

2. *create a simple rest api*

create a file named `main.go` in the `backend` directory.

```go
// backend/main.go
package main

import (
"encoding/json"
"net/http"
)

type message struct {
text string `json:"text"`
}

func hellohandler(w http.responsewriter, r *http.request) {
message := message{text: "hello from go!"}
json.newencoder(w).encode(message)
}

func main() {
http.handlefunc("/api/hello", hellohandler)
http.listenandserve(":8080", nil)
}
```

3. *create a dockerfile for the backend*

create a file named `dockerfile` in the `backend` directory.

```dockerfile
backend/dockerfile
from golang:1.18-alpine as builder
workdir /app
copy . .
run go build -o main .

from alpine:latest
workdir /app
copy --from=builder /app/main .
expose 8080
cmd ["./main"]
```

step 3: setting up the frontend (typescript)

1. *initialize a typescript project*

navigate to the `frontend` directory.

```bash
cd ../frontend
npm init -y
npm install express @types/express typescript ts-node nodemon --save-dev
`` ...
