Could anyone please suggest how to achieve this.

I have created an AMAZON RDS mariadb database under free tier.

I used a random generated password first but it is not connecting.

So, I click modify and updated the database with new password.

but still, I am getting error as below.

(conn=36) Access denied for user 'root'@'175.101.107.213' (using password: YES)
Current charset is windows-1252. If password has been set using other charset, consider using option 'passwordCharacterEncoding'

But I updated the password multiple times but same issue everytime.

Please suggest how to fix that. I checked the passwordCharacterEncoding option in the dbeaver, it is having an empty value.

Whenever I create a VM, it is taking directly from "Public IP Addresses - Basic" quota,when it will use standard? And where to set that?

And what is the difference between them?

I have created aks cluster with azure network type selected.

Terraform files for reference

My VNet used with aks.

But this vnet is not available in the dropdown of azure postgres flexible server creation.

I have created postgres with private vnet option. So, no direct access to posgres from internet.

But, I can't access it from "CloudShell" also.

Also, while creating database,when I want to choose existing VNets, aks cluster(VNet) is not showing in the drop down.

How to keep AKS(azure kubernetes service) cluster and postgres flexible server in the same network then?

Even I tried VNet linking for time being, but not working the connectivity there also.

I ran pip freeze command with my jenkins job and below is the output

pip freeze 
fpdf==1.7.2
textfile==0.1.4

pip install textfile 
Requirement already satisfied: textfile in c:\python39\lib\site-packages (0.1.4)

But when I ran the python script as a job, getting error as below.

 $ python C:\Users\ADMINI~1\AppData\Local\Temp\jenkins2938633000292670144.py
Traceback (most recent call last):

    import textile
ModuleNotFoundError: No module named 'textile'

Let's say I have branch fetaure1, where there is pipeline file.

The trigger will be like this.

trigger:
   - feature1

For development purpose, I created a new branch from it say (feature1_deveoper1)

But, even though this new branch has this pipeline file, need to modify this again to get trigger working from it.

trigger:
   - feature1
   - feature1_developer1

So, after all my work, let's say I want to merge to the feature1 branch, again I need to remove this new feature entry and merge it to the branch.

Any better approach for this situation?

In github actions, we can set this using

- name: Build with Maven
  working-directory: ./VaultService
  run: mvn clean package --file pom.xml
  env:
    CI: false

But there is no working-directory option in azure devops.

Even I tried below one, but it is not building in the VaulService folder.

- task: Maven@3
  inputs:
    mavenPomFile: 'pom.xml'
    goals: 'clean package'
    options: '-DbuildDirectory=VaultService'
    publishJUnitResults: false
    javaHomeOption: 'JDKVersion'
    mavenVersionOption: 'Default'
    mavenAuthenticateFeed: false
    effectivePomSkip: false
    sonarQubeRunAnalysis: false

I kept trigger to cloud_singlesignon branch.

But my pipeline saved to azure-pipelines and the default branch to the repo is master.

But the checkout not happening from cloud_singlesignon.

I observed, it is checking out from branch where the pipeline is saved(azure-pipelines), not the one in trigger

Any idea how to troubleshoot this?

my pipeline:

trigger:
- cloud_singlesignon
 
resources:
  - repo: self
 
pool:
  vmImage: ubuntu-latest
 
steps:
- script: echo Hello, world!

    git log --oneline | wc -l

I have installed adopt openjdk 16 using the task below.

steps:
- script: echo Hello, world!
  displayName: 'Run a one-line script'

- script: |
    wget https://github.com/adoptium/temurin16-binaries/releases/download/jdk-16.0.2%2B7/OpenJDK16U-jdk_x64_linux_hotspot_16.0.2_7.tar.gz

    cleanDestinationDirectory: true
- script: |
    java -version
    ls -lRt
    pwd
    ls $(Pipeline.Workspace)

I download the jdk with step 1 and installed it using step 2 "JavaToolInstaller@0"

I didn't find such for maven, can anyone please suggest.

I saw few links where I can tag my docker image using ${Build.SourceVersion} in azure devops pipeline.

But it is using the complete ID of the commit.

But I want to use only the short ID.

I mean this (2cc7968) instead of this (2cc79689fc29ad69698d3062688e2a650da62b8e)

How to get this?

Is there any way to keep the pipeline file separately in a different repo than the one in source code?

So that, we can maintain all the pipelines related data in a separate repository but the pipeline should detect changes from the main repo.

Example:

I have a repo my-code-base and instead of creating pipeline in my-code-base, I will create a separate repo my-infra and save the pipeline files there.

But in the pipeline I should set the code should be picked from my-code-base.

Please suggest.

If it works, we can save all the azure devops CI/CD pipelines in my organization to be maintained separately.

I am using hyper-v as a hypervisor and installed ubuntu 21 on it.

There, whenever I start the VM, the eth0 (only one network interface connected,Default Switch of Hyper-v) is not getting IP and showing as down.

Please bare with my snaps, as I can't ssh to the machine to copy the output and paste here as text.

There is no /etc/network/interfaces file on my machine, as many forum questions modifying content on this file.

To make this network adapter up, I ran below command.

sudo ip link set eth0 up

Then, the network adapter is up now but without ip4 address.

To get ip address, I ran below command and it gets ip.

sudo dhclient eth0

Then, I get IPv4 address.

I need to do this every time I on the machine.

How to fix this?

How to get projects having admin users or list of them if multiple admin users on them using API?

When I am trying to edit the task sequence and add my own script, the ps1 file is not downloading on the target machine and not running.

Attached the screenshot.

I copied the ps1 file to Deployment share\scripts folder

I have tried using kustomize to load properties file as a configmap.

For that, I created a sample set as in github link.

With base files:

#kustomize build base
apiVersion: v1
data:
  config: |-
    dbport=1234
    dcname=sfsdf
    dbssl=false
    locktime=300
    domainuser=
kind: ConfigMap
metadata:
  labels:
    owner: sara
  name: database-configmap
---
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nginx
    owner: sara
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx

        app: nginx
        owner: sara
    spec:
      containers:
      - image: nginx
        name: nginx

With external file:

#kustomize build file
apiVersion: v1
data:
  config: "dbport=156767\r\ndcname=dfsd\r\ndbssl=false\r\nlocktime=300\r\ndomainuser=somedts"

If you observe the configmap | is removed and also replaced by \r\n as a single string. How to fix this alignment?

If you observe above, the ConfigMap is being discarded, please suggest how to fix that.

I have a jenkins production job which involves multiple nodes/slaves and when we run the job it utilizes them based on the slave mentioned. And also, it has access to some machines shared folders.So from master, it is trying to access shared folders like \machine1\c$\sharefolder1 \machine2\c$\sharefolder2

So for my test environment, I installed jenkins and want to keep everything in a single slave. But,I don't want to modify the jobs.

So, I added entries in my local machine where jenkins is running and added entries to hosts file for machine1 and machine2. \localhost\c$ is opening but not with \machine1\c$ or \machine2\c$ even after adding entries to hosts file.

# localhost name resolution is handled within DNS itself.
    127.0.0.1       localhost      machine1     machine2 

ping is redirecting to 127.0.0.1 loopback address only. But with localhost or 127.0.0.1 it is not prompting for password.But for machine1 or machine2 it is prompting for credentials and typing the machine's credentials is not working.

When I apply a label to Node, it is working as expected and the job able to pick this node.

But, if I apply multiple labels, it is not working. As I observe, it is taking both of them as single label.

Example: label: devbuild

It is working with the job.

But,

label: devbuild,installernode

It is not working for any of the jobs with label "devbuild" or "installernode" Even I tried with ; but same issue.

Please suggest how to apply multiple labels to single node.
