20 | - After filling up the details, click on the Create Account and Continue button at the bottom of the form.
21 | - You need to enter your Credit Card details.
22 | - However, don’t worry. This will not charge anything from your account (except for a verification amount that will be refunded back). But this is required in case you exceed the free-tier limit available with a new AWS Account.
23 | - After entering the details, click on Secure Submit button. It might take a while to process the request depending on your bank/credit card company servers.
24 | - Once the credit card details are confirmed, you will need to complete the Identity Confirmation step.
25 | - Basically, you need to select a mode to confirm your identity. It could be a Text Message or a Voice call to your valid phone number.
26 | - we need to select the plan for our AWS Account.
27 | - Unless you are planning to do some professional development, i would suggest selecting the Basic Plan. It is Free of cost and great for learning purposes.
28 | - Once you select your plan, you will see the below Welcome screen. From here on, you can Sign in to your AWS Console. Here, you also have the option of personalizing your experience of using Amazon Web Services.
29 | - However, you can also simply continue by clicking Sign in to the Console. After this, you will be again presented with the sign in screen where you can now use your credentials to login.

35 | - Step 2 - Click (BILLING PREFERENCES)
36 | - Step 3 - Select (Receive free tier usage alerts -> Give ur email which u registered)
37 | 
38 | #### Payment methods
39 | - Dont enable (enable recruiting payment for default payment methods)
40 | 
41 | ## Service Quotas
42 | 
43 | #### For every service there is limit to create quotas
44 | - Click on ur profile name (service quotas)
45 | ##### If you want to create more than quotas which they assigned u need to create a case to aws
46 | 
47 | 
48 | #### Support Center 
49 | - Click on (?) 
50 | - Click on (support center) 
51 | - Click on (create case){looking for service limit increase}
52 | - Click (service limit increase) 
53 | ##### You provide the details 
54 | - Limit type (ec2 instance) 
55 | - Choose the (region)
56 | - Choose the instance type (p instance) -> New limit value (500) 
57 | ##### Likewise you have to request

102 | ```
103 | ```
104 | eksctl version
105 | ```
106 | 
107 | ### Create EKS Cluster using eksctl
108 | 
109 | It will take 15 minutes to 20 minutues. execute below command at together 
110 | 
111 | ```
112 | eksctl create cluster --name=eksdemo1 \
113 |                       --region=us-east-1 \
114 |                       --zones=us-east-1a,us-east-1b \
115 |                       --without-nodegroup 
116 |                       
117 | ```
118 | 					  
119 | 								  
120 | Get List of clusters
121 | 
122 | ```
123 | eksctl get cluster
124 | ```
125 | ### Create & Associate IAM OIDC Provider for our EKS Cluster
126 | If u want to use everything effectively following in order is the best execute below 
127 | ```
128 | eksctl utils associate-iam-oidc-provider \
129 |     --region us-east-1 \
130 |     --cluster eksdemo1 \
131 |     --approve
132 | ```
133 | 
134 | 
135 | ### Create EC2 Keypair
136 | 
137 | - Create a new EC2 Keypair with name as kube-demo #better u select pem 
138 | 
139 | This keypair we will use it when creating the EKS NodeGroup.
140 | This will help us to login to the EKS Worker Nodes using Terminal.
141 | 
142 | ### Create Node Group with additional Add-Ons in Public Subnets
143 | Create Public Node Group   
144 | 
145 | what all we create 
146 | ```
147 | eksctl create --help  
148 | ```
149 | what all options available for node group we can see here 
150 | ```
151 | eksctl create nodegroup --help 
152 | ```
153 | It will take 3 to 5 minutes. It will create t3.medium nodes with minimum 2 and maximum 4 
154 | ```
155 | eksctl create nodegroup --cluster=eksdemo1 \
156 |                        --region=us-east-1 \
157 |                        --name=eksdemo1-ng-public1 \
158 |                        --node-type=t3.medium \
159 |                        --nodes=2 \
160 |                        --nodes-min=2 \
161 |                        --nodes-max=4 \
162 |                        --node-volume-size=20 \
163 |                        --ssh-access \
164 |                        --ssh-public-key=kube-demo \
165 |                        --managed \
166 |                        --asg-access \
167 |                        --external-dns-access \
168 |                        --full-ecr-access \
169 |                        --appmesh-access \
170 |                        --alb-ingress-access 
171 | ```
172 | 
173 | Sometimes it will fail and it will recreate again 
174 | List of nodes available
175 | ```
176 | kubectl get nodes -o wide
177 | ```
178 | - Take the pubic ip of created t3.medium nodes and do ssh with kube-demo as a pem file
179 | 
180 | ## Delete EKS Cluster
181 | 
182 | ### Delete Node Groups
183 | ```
184 | # List EKS Clusters
185 | eksctl get clusters
186 | 
187 | # Capture Node Group name
188 | eksctl get nodegroup --cluster=eksdemo1
189 | 
190 | # Delete Node Group
191 | eksctl delete nodegroup --cluster=eksdemo1 --name=eksdemo1-ng-public1
192 | ```
193 | 
194 | ## Delete Cluster
195 | ```
196 | eksctl delete cluster eksdemo1
197 | ```

 1 | # Create Virtual Machine in AWS Cloud
 2 | 
 3 | Go to AWS Management Console -> Ec2 -> Launch Instance 
 4 | - Step 1: Choose an Amazon Machine Image (AMI) -> [Amazon Linux 2 AMI (HVM) - Kernel 5.10, SSD Volume Type ]
 5 | - Step 2: Choose an Instance Type -> [t2.micro]
 6 | - Step 3: Configure Instance Details -> Number Of Instances [1] (usually we deploy in custom vpc)
 7 | - Step 4: Add Storage  -> [do not change any]
 8 | - Step 5: Add Tags -> Name  Server
 9 | - Step 6: Configure Security Group (port 22 should be opened) #by default its opened in AWS 
10 | - Step 7: Key Pair - Create a key pair (Name -> mypersonalkey, Select (.pem), click (Download)) # Note: Don't loose pem file
11 | - Step 8: Review And Launch
12 | ### Connect to server using session manager in the AWS 
13 | - login: ec2 - user
14 | - sudo su -
15 | ###  Connect to server using mobaxterm
16 | - Click (Mobaxterm)
17 | - Click (Session)
18 | - Click (SSH)
19 | - Remote Host - Give IP(Public)
20 | - Click (Advanced SSH settings 
21 | - Select (use private key - Give(Pem file))
22 | - Click (ok)
23 | - login: ec2 - user
24 | 
25 | ### Elastic IP
26 | Elastic IP address is a static IPv4 address designed for dynamic cloud computing. An Elastic IP address is allocated to your AWS account, and is yours until you release it.
27 | #### If you want to allocate Elastic IP for entire region its billable
28 | - Step 1 - You can see under network and security (or) Search (Elastic Ip) in AWS management console
29 | - Step 1.1 - click (Elastic Ip) 
30 | - Step 2 - click on (allocate elastic ip address) 
31 | - Step 3 - Let all be default, click (allocate). Now u have got an elastic ip 
32 | - Step 4 - click on (actions -> associate ec2 instance -> select which ec2 instance u need to associate)
33 | #### If you don't want to assign Elastic IP to the server
34 | - Click (elastic ip) -> (actions -> deassociate elastic -> diassociate) -> (actions -> release elastic ip address) 
35 | 
36 | 
37 | #### AWS Pricing Calculator 
38 | Lets you explore AWS services, and create an estimate for the cost of your use cases on AWS.
39 | 
40 | - Step 1 - search (Aws Pricing calculator) in Browser/google (or) https://calculator.aws/#/
41 | - Step 2 - click (Create estimate)
42 | - Step 3 - To estimate the cost 
43 | ##### Example: Search (EC2) -> click (Configure) -> (region - N virginia) -> operating system  (linux) -> instance type (search instances by name (t2.micro) u can see on demand hourly cost -> utilixzation (24/7 for 30 days (100)) -> pricing strategy (ondemand ec2 instance) -> EBS (30) -> you can see total monthly cost.
44 | Its like a pay as you go model. Storage is chargable even u stop server (cpu, memory not charged)

47 | 
48 |         - To solve this issue we need to add current user to docker group , to do the same follow the below commands 
49 |           sudo groupadd docker
50 |           sudo usermod -aG docker $USER ( got a error while runing docker commands with the current user)
51 |           sudo usermod -aG docker jenkins (got a error while runing docker commands with jenkins user )
52 |           getent group <groupname> (to check the list of users in particular group)
53 |           sudo passwd jenkins to change password of jenkins user
54 |         
55 |         - even after following the above commands if you face any issue in ruuning commands then run below command
