A collection of my learnings, notes and musings on Docker.

These are currently random notes and are not much help to anybody yet. They will get tidied as I add to the page.

Docker Swarm

Docker swarm secrets

From inside a docker swarm manager node, there are two ways of creating a secret.

Using a string value:

printf <your_secret_value> | docker secret create your_secret_key -

Using a file path:

docker secret create your_secret_key ./your_secret_value.json

Docker swarm secrets are saved, encrypted, and are accessible to containers via a filepath:

/run/secrets/your_secret_key.

Been learning to use Docker Swarm

Despite not yet managing to get what I have learnt implemented, I have nonetheless took on board some good concepts around docker and docker swarm

After getting half-way through a Docker Mastery series on Udemy, I decided I would like to move my WordPress website, this one, to using a 3-node swarm.

After a few days of editing and re-arranging my docker-compose.yml file (the local dev configuration file that can also be used for starting up a swarm since compose version 3.3) I have decided to just keep my website hosted on its single regular server. (Although I had already moved the database to its own dedicated server).

Despite the fact that I haven’t actually managed to move over to using a swarm (and to be honest it isn’t even needed for me) I have managed to dive into a bunch of concepts around Docker and its Swarm component and feel that I have added a few new things to me dev toolkit.

I think I will definitely be putting together a little demo in a swarm across three separate servers. But for now I will keep my website settled as it is. 😀

What I have learned – or rather reminded myself of, whilst sat in at home during this damn isolation, is that it is important to keep looking into complimentary technologies around my everyday development skill set.

The Art of Junji Ito: Twisted Visions can now be pre-ordered

The upcoming book, The Art of Junji Ito: Twisted Visions, is now available for pre-order at the following places:

Amazon

Book Depository

Waterstones

It will be officially released on the 14th May 2020.

From the picture above it looks like its a good size too — a little larger than A4 size I reckon. All the better to focus in on Junji Ito’s excellent craftsmanship and twisted imagery.

I’m looking forward to this one as it looks to contain many pieces of Junji Ito’s original artwork. Perhaps even some that were cut from some of his stories?

How excited are you for this new book?

New horror manga – Genkai Chitai (Disturbing Zone) released in Japan

Junji Ito has launched a brand new horror manga called Genkai Chitai, which is Japanese for Disturbing Zone.

Junji Ito has launched a brand new horror manga called Genkai Chitai, which is Japanese for Disturbing Zone. It seems to be a part of a new horror omnibus series called “Phantom Zone”.

From what I can find out so far, it revolves around the more mundane aspects of every day life and how strange occurrences around those things happen. No doubt bringing weird and interesting horror themes into the lives of some very unsuspecting characters.

It has been released through a publication called “Line”. I have found a website called Line Manga, however, it is only available to be viewed from Japan. 🙁

I’m really looking forward to reading this one and can’t wait for an official U.K. release.
