Runinng a Spring boot application with an external application.properties

Some times we are going to need running a Spring boot application with its application.properties outside of the jar, sometimes you just move your final .jar to another server, or sometimes, you just need to change your Spring boot application port or database credentials among other settings, so to this without recompiling and packaging everything again we just copy the application.properties at the same level of the .jar file and that's it you can now change your application.properties any time without recompiling everything.

in this case, I have got an end .jar file name Generic-0.0.1-SNAPSHOT.jar, and I copied the application.properties of the project and paste it at the same level where I run
java -jar Generic-0.0.1-SNAPSHOT.jar allowing me to do changes just editing that application.properties.

For SSL/TLS certificates, there are a small number of providers (e.g. Symantec/Versign/Thawte, Comodo, GoDaddy, LetsEncrypt) whose certificates are included by most browsers and Op...

How to deploy a VueJS App using Nginx on Ubuntu

There are thousands of blogs and websites out there explaining how to do a hello world and how to start with VueJS, but in this little post, I’m just going to be explaining how to do deploy a VueJs app after you have run the command through the CLI npm run build . So when you run the command npm run build a dist folder is created and that folder’s got the essential .js files to run our app, when we want to run our app on an Nginx server by default the vue-router is not going to work well so that Nginx does not come ready to work by default with a VueJs app This is basically for a Linux Ubuntu distribution if you’ve got any other Linux distribution just pay attention where is going to be set the www/html folder and the Nginx settings so that this is useful for any Linux distribution  Install and configure nginx sudo apt install nginx Double check to make sure the nginx service is running with command service nginx status, then open your browser and enter ...
