# Try Out Development Containers: Go
|
|
|
|
This is a sample project to go along with the "Try a dev container" quick start for the **[VS Code Remote - Containers](https://aka.ms/vscode-remote/containers)** extension.
|
|
|
|
**If you are not yet in a development container, [see below](#setting-up-the-development-container).**
|
|
|
|
## Things to try
|
|
|
|
Once you have this sample opened in a container, you'll be able to work with it like you would locally.
|
|
|
|
Some things to try:
|
|
|
|
1. **Edit:**
|
|
- Open `server.go`
|
|
- Try adding some code and check out the language features.
|
|
2. **Terminal:** Press <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
|
|
2. **Build, Run, and Debug:**
|
|
- Open `server.go`
|
|
- Add a breakpoint (e.g. on line 22).
|
|
- Press <kbd>F5</kbd> to launch the app in the container.
|
|
- Once the breakpoint is hit, try hovering over variables, examining locals, and more.
|
|
- Continue, then open a local browser and go to `http://localhost:9000` and note you can connect to the server in the container.
|
|
3. **Forward another port:**
|
|
- Stop debugging and remove the breakpoint.
|
|
- Open `server.go`
|
|
- Change the server port to 5000. (`portNumber := "5000"`)
|
|
- Press <kbd>F5</kbd> to launch the app in the container.
|
|
- Press <kbd>F1</kbd> and run the **Remote-Containers: Forward Port from Container...** command.
|
|
- Select port 5000.
|
|
- Click "Open Browser" in the notification that appears to access the web app on this new port.
|
|
|
|
## Setting up the development container
|
|
|

|
|
|
|
2. If you're not yet in a development container:
|
|
- Clone this repository.
|
|
- Press <kbd>F1</kbd> and select the **Remote-Container: Open Folder in Container...** command.
