Containers, Dockers and Spring Boot walk-through

-

Introduction to Basic docker Commands:

docker run - Image -- creates a container from an image. If you run this many times you create many containers from the same image docker start name |id - Starts an existing container that is not running docker stop name|id docker ps ( -a include stopped containers) docker rm name|id --Remove a container docker rmi imageName-- Remove docker image docker run -it ubuntu when -i -t is added, it gives an interactive shell access into the container. Without this the container runs and exits! To get started create and account here: https://hub.docker.com/ Making a new image from the original image docker run -it ubuntu -- If the image is not available docker will pull from hub.docker.com sudo apt-get install nodejs example: docker commit -m "added node.js" -a "Chris Kibuchi" 96ac46a4d14f ckeidev/ubuntu-nodejs -m for Message -a for Author Login to Dockerhub on terminal: docker login -u ckeidev docker hub username/password docker push ckeidev/ubuntu-nodejs ====Spring Boot==== https://spring.io/guides/gs/spring-bo... docker run -e "SPRING_PROFILES_ACTIVE=dev" -p 8080:8080 -t ckeidev/gs-rest-service this will launch the docker with spring boot and -p maps a port on docker to the host machine port -p hostport/dockerport

Database Version: Oracle 12c To start with, Create a pluggable(container) before you import your data. (You have to be logged in to your database)  eg. sqlplus sys as sysdba Step 1: Use the command below to create pluggable CREATE PLUGGABLE DATABASE <your_container_name> ADMIN USER PDB_ADMIN IDENTIFIED BY oracle FILE_NAME_CONVERT = ('/oradata/orcl/pdbseed/','/oradata/orcl/ <your_container_name> '); Note: username  oracle  in this case is the admin user for your database that you configured during installation. Step 2: Run these commands in order: alter session set container=<your_container_name>; startup; execute this on a new terminal tab to create pdb folder manually: mkdir -p /oradata/orcl/<your_container_name> Step 3: Execute the following 7 commands inside your container in their order: 01. CREATE OR REPLACE DIRECTORY PLUGGABLE_DATA_PUMP_DIR as '/oradata/orcl/<your_container_name>'; 02. GRANT REA...

In this post I am going to share with you the circuit diagram, code and how to fix faint display or completely invisible texts on the screen. Final Product Components -  Arduino  Uno board - 1 * Breadboard - 1 * USB data cable (To connect the board to your PC) - 1 * LM35 Temperature Sensor - 1 * I2C LCD1602 (QPASS LCD Display) - Several jumper wires LM35 Circuit For this project you need to add LiquidCrystal Library to your Arduino IDE. In this case I am using V1.07 Download and install by selecting the zip as shown below CODE: // This sketch tests the standard 7-bit addresses // Devices with higher bit address might not be seen properly. // #include void setup() {   Wire.begin();   Serial.begin(9600);   Serial.println("\nI2C Scanner"); } void loop() {   byte error, address;   int nDevices;   Serial.println("Scanning...");   nDevices = 0; ...
