Ok, I just managed to run the docker container conencted to the created networrk.
I had to run

Code:

$ docker rm bitcoind
$ docker run -it --network lnbook --name bitcoind lnbook/bitcoind

That's correct; even if you stopped the docker container, it still 'existed' and you therefore need to delete / remove it (rm).

If you followed the book step by step, I'd honestly consider this a 'bug' / error and would recommend to create an issue with description and fix (those 2 terminal commands).

Yes maybe. I just need to fix another problem that just came up following this steps. But this is probably on my side.
After I wasa able to run the 2 containers connected to the same network, I tried to start the container for lnd but I failed to run the command correctly and got errors. Then, I spotted the problem and I ran the command with a small typo.
So, I run this:

Code:

$ docker pull lndbook/lnd
Using default tag: latest
Error response from daemon: pull access denied for lndbook/lnd, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

instead of running:

Code:

$ docker pull lnbook/lnd
Using default tag: latest
Error response from daemon: pull access denied for lndbook/lnd, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

It is a typo in lnbook versus lndbook

So, when I ran the wrong command and got that error, I went to search about that and end up finding another similar command in dockerhub. So I ran it:

Code:

$ docker pull lncm/lnd
Using default tag: latest

But then, when I tried to move on, I got errors. I skipped some of the output because it's too long. It starated well, but then...

I skipped some of the red output because it is too long.

Now, I don't know if this is because I ran the other command and tried to run this command or if this is due to something else.
I think I'll simply delete all the lnbook folder and will try again, from the beginning.

Hi.

I started reading this book, written by Antonopoulos, Osuntokun and Pickardt, right at github, here.

I have created this thread to ask questions about the contents of the book whenever I'm unable to understand a sentence, a subject, an example or watever question I may have.

If others also want to ask questions on top of my questions, feel free but I would like to keep the thread kind of limited to my questions and people's answers so that I don't lose focus on each question/answer.

I find this book very interesting based on its area of focus and am interested in this book reading it too and would love to follow up with you in this thread on future questions that might arise from you for more understanding. But I may not be putting down questions for the sake of not to intercept yours.

I think you can ask questions here if you're also reading the book. You are free to do so. I think we will manage a
