How to use Ngrok with docker, multiple tunnels, ssh to local VMs

In my previous video ( • How to use docker and ... ) I've shown you how to use cloudflare tunnel to expose local service to the internet via docker.
If you do not have your own domain, you can use cloudflare tunnel and you can use Ngrok instead.
In today's video, I will walk you through some basics of using Ngrok with docker.

very helpful video, keep it up~~

Thank you for the detail instructions. However, when I tried to use micro command on ngrok.yaml I got "-sh: micro: command not found" can you please advise? I tried to run ngrok on my synology NAS. Thank you

[@liyangau]

micro is the editor I use. You can use other editors like vi, nano.

@@liyangau Got it. I also notice on the docker run command for network you create new network name ngrok, but what if I want to use default network or using same as docker host? because when I tried to open tunnel as your example using ngrok network that we create, my ngrok tunnel page doesn't show any agent enable. but on the docker using docker ps command it show the ngrok start an running. Sorry, i'm new to this ssh command. Thank you

​@@peterhandjojo3579 I used ngrok network because I like to segregate different components in different docker networks. It is perfectly fine to use the default docker network as long as ngrok container can access the service you want to expose.
Also please don't be sorry for asking questions. It is my pleasure to help.
Have a good day.
