Try out dksnap

This directory contains an example node application that stores data in mongo. Shout out to the original author, scotch-io.

The following instructions will walk you through using dksnap to create a snapshot, and rollback to it. Click the image below to view a video of the demo.

1. Download the demo

$ git clone https://github.com/kelda/dksnap
$ cd dksnap/demo

2. Boot the app

$ docker-compose up -d

This will boot the node and mongo containers. Once they're up, access the todo UI at http://localhost:8080.

3. Create a snapshot of mongo

This will let us rollback to the empty database later.

Start dksnap by running dksnap, select the mongo container, and enter the snapshot form by hitting [Enter].

Then, title your snapshot "No todos", and hit [Enter] on "Create Snapshot".

4. Add a todo item at http://localhost:8080

5. Rollback to the "No todos" snapshot

Switch to the "View snapshots" tab in dksnap using Ctrl-N, and select the "No todos" snapshot.

Then, hit [Enter], select "Replace Running Container", and select the mongo container.

6. Confirm that the database was rolled back

Refresh http://localhost:8080 and make sure that there are no todo items.
