Increasing the amount of inotify watchers in Arch Linux

If you are running ArchLinux, run the following command instead (see here for why):

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Then paste it in your terminal and press on enter to run it.

1. Create a bridge network for the containers docker network create app01net

2. Run MongoDB Docker Container docker run --name mongoserver --network app01net mongo:latest This will make mongodb://mongoserver available (not port needed)

3. Run NodeJS environment mkdir application docker run --rm -it -w="/usr/src/app" -p 3000:3000 -v $PWD/application:/usr/src/app:z --network app01net node:latest bash

1. Create DOcker container with MySQL version 5.7

$ docker run --name wp-mysql -v C:\my-docker-volumes\wp-mysql:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=wp -d mysql:5.7

2. Create the WordPress container, by linking to created DB

$ docker run --name wp-docker --link wp-mysql:mysql -v C:\my-docker-volumes\wp-site\themes:/var/www/html/wp-content/themes -v C:\my-docker-volumes\wp-site\plugins:/var/www/html/wp-content/plugins -p 8080:80 -e WORDPRESS_MYSQL_PASSWORD=wp -d wordpress

3. Run WP-CLI commands using Docker

docker run -it --rm --volumes-from wp-docker --network container:wp-docker wordpress:cli user list docker run -it --rm --volumes-from wp-docker --network container:wp-docker wordpress:cli scaffold child-theme my-child --parent_theme=twentynineteen

I found this in a Microsoft Help Forum (https://answers.microsoft.com/en-us/windows/forum/windows_10-performance/service-host-local-system-constantly-using-cpu-and). I googled this issue for a long time, I tried scandisk, defrag, I also read many articles with 10 tips for fixing 100% disk and nothing really solved the issue until this.

Here is the answer that helped me: fucking WSReset.exe - IT RESETS THE GODAMN WINDOWS STORE and all the sudden the 100% disk went to 12%. Now is currently 4%, I am watching youtube stream and have a couple of tabs opened, also the Store. Now is 1% and then 6% etc. Amazing.

To run it, just type WSReset.exe on Run, on a terminal or even on a Windows Explorer address bar. It will take some time to run, and then load the windows store.

docker run --rm -it -w="/usr/src/app" -v $PWD/application:/usr/src/app:z --user $(id -u):$(id -g) node bash

Add ports as needed, example:

docker run --rm -it -w="/usr/src/app" -p 8080:8080 -p 3000:3000 -v $PWD/application:/usr/src/app:z --user $(id -u):$(id -g) node bash

Example: Developing Angular Apps with Docker

docker run --rm -it -w="/usr/src/app" -p 4200:4200 -v $PWD/application:/usr/src/app:z --user $(id -u):$(id -g) node bash then create a new project inside the docker terminal

Setup private Ethereum network with Docker

Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.

This is a step-by-step guide, how to setup private Ethereum network. 

We’ll set up a network and create two simple JSON-RPC clients in order to communicate with our Ethereum nodes.
