Task 𝟭𝟮 of KodeKloud's 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 - 𝗟𝗲𝘃𝗲𝗹 𝟭 curriculum. Today's task was to Update Deployment and Service in Kubernetes.

After a deployment and services has been executed, sometime you have make an update. In cases like this, having the chops to fix the issue is a must!

Here's today's task requirements:

The deployment is named 𝗻𝗴𝗶𝗻𝘅-𝗱𝗲𝗽𝗹𝗼𝘆𝗺𝗲𝗻𝘁. The service is called 𝗻𝗴𝗶𝗻𝘅-𝘀𝗲𝗿𝘃𝗶𝗰𝗲
Modify the service nodeport from 30008 to 32165
Change the replicas count from 1 to 5
Update the image from 𝘯𝘨𝘪𝘯𝘹:1.19 to 𝘯𝘨𝘪𝘯𝘹:𝘭𝘢𝘵𝘦𝘴𝘵

Here's how I completed this task:

Update the service using the 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚎𝚍𝚒𝚝 command to update the configuration:

𝚞𝚜𝚎𝚛@𝚓𝚞𝚖𝚙-𝚑𝚘𝚜𝚝 ~$ 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚎𝚍𝚒𝚝 𝚜𝚎𝚛𝚟𝚒𝚌𝚎𝚜 𝚗𝚐𝚒𝚗𝚡-𝚜𝚎𝚛𝚟𝚒𝚌𝚎

Change this line from 30008 to 32165:

Before:

𝚜𝚙𝚎𝚌:
- 𝚗𝚘𝚍𝚎𝙿𝚘𝚛𝚝: 𝟹𝟶𝟶𝟶𝟾
After:

𝚜𝚙𝚎𝚌:
- 𝚗𝚘𝚍𝚎𝙿𝚘𝚛𝚝: 𝟹𝟸𝟷𝟼𝟻
Then save it:

𝚜𝚎𝚛𝚟𝚒𝚌𝚎/𝚗𝚐𝚒𝚗𝚡-𝚜𝚎𝚛𝚟𝚒𝚌𝚎 𝚎𝚍𝚒𝚝𝚎𝚍
Verify by viewing the services:

𝚞𝚜𝚎𝚛@𝚓𝚞𝚖𝚙-𝚑𝚘𝚜𝚝 ~$ 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚐𝚎𝚝 𝚜𝚎𝚛𝚟𝚒𝚌𝚎𝚜 𝚗𝚐𝚒𝚗𝚡-𝚜𝚎𝚛𝚟𝚒𝚌𝚎

𝙽𝙰𝙼𝙴 𝚃𝚈𝙿𝙴 𝙲𝙻𝚄𝚂𝚃𝙴𝚁-𝙸𝙿 𝙴𝚇𝚃𝙴𝚁𝙽𝙰𝙻-𝙸𝙿 𝙿𝙾𝚁𝚃(𝚂) 𝙰𝙶𝙴

𝚗𝚐𝚒𝚗𝚡-𝚜𝚎𝚛𝚟𝚒𝚌𝚎 𝙽𝚘𝚍𝚎𝙿𝚘𝚛𝚝 𝟷𝟶.𝟺𝟹.𝟷𝟷𝟶.𝟷𝟿𝟷 <𝚗𝚘𝚗𝚎> 𝟾𝟶:𝟹𝟸𝟷𝟼𝟻/𝚃𝙲𝙿 𝟷𝟶𝚖
Next, edit the deployment for the replicaSet count and the image:

𝚞𝚜𝚎𝚛@𝚓𝚞𝚖𝚙-𝚑𝚘𝚜𝚝 ~$ 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚎𝚍𝚒𝚝 𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝 𝚗𝚐𝚒𝚗𝚡-𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝

Relevant lines before change:

𝚜𝚙𝚎𝚌:

𝚛𝚎𝚙𝚕𝚒𝚌𝚊𝚜: 𝟷

𝚜𝚙𝚎𝚌:
```
 𝚌𝚘𝚗𝚝𝚊𝚒𝚗𝚎𝚛𝚜:                                  

 - 𝚒𝚖𝚊𝚐𝚎: 𝚗𝚐𝚒𝚗𝚡:𝟷.𝟷𝟿
```
Relevant lines after update:

𝚜𝚙𝚎𝚌:

𝚛𝚎𝚙𝚕𝚒𝚌𝚊𝚜: 𝟻

𝚜𝚙𝚎𝚌:
```
 𝚌𝚘𝚗𝚝𝚊𝚒𝚗𝚎𝚛𝚜:                                  

 - 𝚒𝚖𝚊𝚐𝚎: 𝚗𝚐𝚒𝚗𝚡:𝚕𝚊𝚝𝚎𝚜𝚝
```
Save the changes:

𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝.𝚊𝚙𝚙𝚜/𝚗𝚐𝚒𝚗𝚡-𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝 𝚎𝚍𝚒𝚝𝚎𝚍
Verify the ReplicaSet now shows 5 pods, instead of 1:

𝚞𝚜𝚎𝚛@𝚓𝚞𝚖𝚙-𝚑𝚘𝚜𝚝 ~$ 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚐𝚎𝚝 𝚛𝚜

𝙽𝙰𝙼𝙴 𝙳𝙴𝚂𝙸𝚁𝙴𝙳 𝙲𝚄𝚁𝚁𝙴𝙽𝚃 𝚁𝙴𝙰𝙳𝚈 𝙰𝙶𝙴

𝚗𝚐𝚒𝚗𝚡-𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝-𝟼𝟾𝟺𝟿𝟾𝟾𝟺𝚋𝟻𝚍 𝟻 𝟻 𝟻 𝟷𝟶𝟽𝚜
Verify the container image updated:

𝚞𝚜𝚎𝚛@𝚓𝚞𝚖𝚙-𝚑𝚘𝚜𝚝 ~$ 𝚔𝚞𝚋𝚎𝚌𝚝𝚕 𝚍𝚎𝚜𝚌𝚛𝚒𝚋𝚎 𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝𝚜 𝚗𝚐𝚒𝚗𝚡-𝚍𝚎𝚙𝚕𝚘𝚢𝚖𝚎𝚗𝚝 | 𝚐𝚛𝚎𝚙 𝚌𝚘𝚗𝚝𝚊𝚒𝚗𝚎𝚛 -𝙰 𝟺

𝚗𝚐𝚒𝚗𝚡-𝚌𝚘𝚗𝚝𝚊𝚒𝚗𝚎𝚛:

𝙸𝚖𝚊𝚐𝚎: 𝚗𝚐𝚒𝚗𝚡:𝚕𝚊𝚝𝚎𝚜𝚝

I hope you found this informative! More to come!
