Udagram is a simple cloud application developed as one of the Udacity Cloud Engineering Nanodegree. The idea of the project is to design, deploy and operate a cloud native photo sharing application.
You need to install the following programs in your computer:
Check if your installation were successful with the following commands:
docker --versionaws --versioneksctl versionkubectl version --short --clientaws-iam-authenticator version
Open your terminal profile to store your application variables:
nano ~/.zshrc
Copy and paste the lines in your file with your values:
export POSTGRESS_USERNAME=(Username of the database);
export POSTGRESS_PASSWORD=(Password of the database);
export POSTGRESS_DB=(Name of the Database);
export POSTGRESS_HOST=(URL Endpoint provided by AWS);
export AWS_REGION=(Region where your database is hosted);
export AWS_PROFILE=(Name of the IAM profile with correct access);
export AWS_BUCKET=(Name of S3 bucket);
export JWT_SECRET=(Random String to use JWT);
source ~/.zshrc
Note: I personally use ZSH terminal in case you use BASH terminal , you will need to enter those values in your .bash_profile
-
First build the images:
docker-compose -f docker-compose-build.yaml build --parallel
-
Second list your docker images to check if they have been built:
docker images
- Third Run your docker containers:
docker-compose up- To exit run
control + C
-
Fourth push your docker images:
docker-compose -f docker-compose-build.yaml push
-
Fifth check your Docker Hub account to check if the images were uploaded:
Copy and paste the script bellow with your cluster name and configuration variables:
eksctl create cluster \
--name udagram-microservices \
--version 1.14 \
--nodegroup-name standard-workers \
--node-type t3.medium \
--nodes 3 \
--nodes-min 1 \
--nodes-max 4 \
--node-ami auto
Note: I created the cluster with " " in the --name flag, but that should be without " " that the reason the name of the cluster is a random one created by AWS.
-
First: encrypt your AWS file, database username and password using base64 using the following commands:
cat ~/.aws/credentials | base64echo POSTGRESS_USERNAME | base64echo POSTGRESS_PASSWORD | base64
-
Second: now add these values in your
env-secret.yaml,aws-secret.yaml, andenv-configmap.yaml. -
Third: load secret files with following commands:
kubectl apply -f aws-secret.yamlkubectl apply -f env-secret.yamlkubectl apply -f env-configmap.yaml- Note: this command to applying to every file
kubectl apply -f .
