Jenkins enviroment installation on Azure

-

1)Install jenkins:

https://docs.microsoft.com/en-us/azure/developer/jenkins/configure-on-linux-vm

in vm creating part use this:

az vm create \

--resource-group QuickstartJenkins-rg \

--name QuickstartJenkins-vm \

--image UbuntuLTS \

--size Standard B2s \

--admin-username "azureuser" \

--generate-ssh-keys \

--custom-data cloud-init-jenkins.txt

in artice use other vm which is cost higher than B2s , but i am using B2s it works very well

2)Install docker:

https://docs.docker.com/engine/install/ubuntu/

Then give permission to docker.sock for build image:

Recommend way second one:

sudo chmod 776 /var/run/docker.sock // for all

sudo chown $USER /var/run/docker.sock // for current user

3)Install openjdk11 for build process, because our spring projects on jdk11

sudo apt install openjdk-11-jdk -y

sudo update-alternatives --config java , then click enter for selecting *

and configure openjdk11 in jenkins global tool configuration

            gcloud compute addresses create ingress-nginx-static-ip  --region us-central1   - create static ip for                ingress-nginx

            gcloud compute addresses list      - show static ip address list

            kubectl patch svc nginx-ingress-ingress-nginx-controller -p '{"spec": {"loadBalancerIP": " 35.239.165.176"}}'     - changing load balancer ip to static

write huge text into clob column in oracle

-
 varchar2 max character size is 32767 , that's why writing huge texts into column is problem. CLOB type is used for this, it can store 2,147,483,647 characters. But it is a bit problematic to write more than 32767 characters into CLOB typed column. For doing that either we should read from file or divide into small chunks. In example we will do this by chunks Firstly: package org.example; import java.io.*; import java.util.ArrayList; import java.util.List; public class FileChunker { private static final int CHUNK_SIZE = 21000; // Size of each chunk public static void main(String[] args) { String filePath = "/Users/bbb/Documents/aaa/new_license/license_en.html"; // Path to your file String outputDir = "/Users/bbb/Documents/aaa/new_license/chunks_en"; // Directory to save chunks try { List<String> chunks = splitFileIntoChunks (filePath); createFilesFromChunks (chunks, outputDir); System. out...
