Step - 10: Once the upgradation_config file is generated, A preview of the upgradation_config file is displayed followed by a question where the user gets an option to re enter the configuration values on choosing yes. If option no is selected then the upgrade.sh moves to the next section.
Step - 11: A preview of the program_selector.yml file is displayed followed by a question where the user gets an option to enable or disable the programs on choosing yes. If option no is selected then the upgrade.sh moves to the next section.
Step - 12: Once the Upgradation is completed, You will be prompted with the following messages and required reference urls.
cQube Upgraded Successfully!
cQube ingestion api can be accessible using <domain_name>
The following steps define the cQube setup and workflow completion processes in AWS. cQube mainly comprises the areas mentioned below:
- 1.EC2 Server
- 2.IAM user and Role creation for S3 connectivity.
The cQube network setup process is described in the block diagram below:
Following are the details of the microservices which get installed in the cqube server.
- Ingestion-ms: The ingestion-ms is used to upload the data of the events, datasets, dimensions, transformers and pipeline. All these apis will be to ingesting the data into the cQube.
- Spec-ms: The spec-ms is used to import schema of the events, datasets, dimensions, transformers and pipeline. All these specs will be defined by the cQube platform prior to ingesting the data into the cQube. These specifications are derived by considering the KPIs as the Indicator.
- Generator-ms: The generator-ms is used to create the specs & transformers for the derived datasets. Performed aggregation logics, updating data to datasets based on transformation. Status update of file processing
- Nifi-ms: Apache NiFi is used as a real-time integrated data logistics and simple event processing platform
- Postgres-ms: Postgres microservice contains the schema and tables
- Nginx-ms: It is commonly used as a reverse proxy and load balancer to manage incoming traffic and distribute it to slower upstream servers
- Kong-ms: It is a lightweight API Gateway that secures, manages, and extends APIs and microservices.
- Dashboard-ms: It consists of an angular app, it is used to visualize the datasets present in postgres-ms in the form of charts. On run time it requests spec-ms to fetch data from postgres-ms and load it into the client side(Browser)
- Query_builder-ms: It consists of backend API, which consists of JWT,METRICS,QUERY apis
JWT - it will generate a jwt token to restrict the other apis.
METRICS - it consists of menus for the navigation bar and dashboard cards.
QUERY - this api used for executing the SQL queries which integrated with Dashboard-ms.
LASTMODIFIED - this api will use for the last modified data in the s3,azure and minio
upgradel.sh sh file contains a shell script where it will run following shell scripts and ansible-playbook to setup the cqube
Basic_requirements.sh:
This script basically updates and upgrades the software packages in the server and installs the basic softwares such as
- Python3
- Pip3
- Ansible
- Docker
- Docker compose
upgradation_Config_file_generator.sh:
This script is used to generate a configuration file which contains some constant values and few required variables should be entered by the user. Following are the variables which get added in the config file.
Note: Users should follow the Hints provided in the description and should enter the variables accordingly. If the entered value is wrong then an error message gets displayed and the user should modify the variable value accordingly.
Constant Variables: These variables are auto generated
- System_user_name
- base_dir
- Private_ip
- aws_default_region
User Input Variables-These are variables which need to be entered by the user by following the Hint provided
- state_name ( Enter the required state code by referring to the state list provided )
- api_end_point ( Enter the url in which cqube to be configured )
- storage_type
Storage_type is aws enter the below variables
- s3_access_key
- s3_secret_key
- s3 bucket name
Storage_type is azure enter the below variables
- azure connection string
- azure account name
- Azure account key
- azure container name
Storage_type is a local system that will automatically create the minio username and minio password and minio bucket.
- minio username
- minio password
- minio bucket
Minino can be accessed by Dashboard with http://localhost:9001 end point, here you can see the minio bucket which is created by default and the username is minioadmin and password is minioadmin
Optional_variables - Database credentials contain default values. If the user wishes to enter their own credentials then the user should opt for yes to enter their credentials otherwise can opt for no when the question pops up
- db_user_name ( Enter the postgres database username )
- db_name ( Enter the postgres database name )
- db_password ( Enter the postgres password )
Optional_variables- Read Only Database credentials contain default values. If the user wishes to enter their own credentials then the user should opt for yes to enter their credentials otherwise can opt for no when the question pops up
- read_only_db_user ( Enter the read only postgres database username )
- read_only_db_password ( Enter the read only postgres password )
Once the upgradation_config file is generated, A preview of the upgradation_config file is displayed followed by a question where the user gets an option to re enter the configuration values on choosing yes. If option no is selected then the upgrade.sh moves to the next section.
Repository_clone.sh:
This script clones the following repositories in the microservices directory and checkout to the required release branch
Note: If the repository is already cloned then the script will pull the updated code.
Ansible-playbook:
upgrade.yml
An upgrade.yml ansible playbook gets triggered where it triggers the required roles to build the following microservices images.
- Ingestion-ms
- Spec-ms
- Generator-ms
- Postgres-ms
- Nifi-ms
- Dashboard-ms
- Query_builder-ms
- Kong-ms
- Nginx-ms
upgrade_compose.yml:
A docker compose ansible script gets triggered where it will up all the containers to running state.
Note: The following commands can be used from the Ansible directory to down the containers and to start the containers, respectively.
- docker-compose -f upgrade_docker-compose.yml down
- docker-compose -f upgrade_docker-compose.yml up -d
Run_api.sh:
Run_api.sh script will run the v4-data-emission api using curl command in the ingestion_ms container. And it will run the adapter file to run VSK_data_transformation.sh script in the generator-ms container.
Once the Upgradation is completed, You will be prompted with the following messages and required reference urls.
