Installations:

Prerequisites:

• Node 18

  Can be installed using nvm. Run following commands to install node

  $ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
  $ nvm install 18

• Docker

  • Install on Ubuntu
  • Docker Desktop for Windows
  • Other platforms

• Docker Compose

  Note: Requires installation of Docker. This step can be skippped if Docker desktop(Windows) is installed as it comes along with docker compose. Please install Docker using above links before proceeding for the installation of docker compose

  • Install as plugin to docker command
  • Install the Compose standalone

  Once installed, use Docker compose option below to run the Inji Verify application for a quick demo.

---

Folder Structure:

Once the repo is cloned, following folders can be found under the inji-verify repository folder:

• helm: folder contains helm charts required to deploy on K8S
• inji-verify: contains the application source code, Dockerfile and docker-compose.yml files
  • src (source code)
  • Dockerfile
  • docker-compose.yml
• ui-test: contains the ui automation tests

---

Configuration:

The configuration to the Inji Verify application can be passed using the .env file which is present inside the inji-verify folder.

It accepts INTERNET_CONNECTIVITY_CHECK_ENDPOINT and INTERNET_CONNECTIVITY_CHECK_TIMEOUT variables at this moment. These are used to check the availability of the internet connection and can be configured when required. The default values are added in the .env file.

---

Developer Setup:

Once the repo is cloned, move into the inji-verify repository folder and run the following command to check out to the develop branch:

cd inji-verify # move into the repository folder
git checkout develop
cd inji-verify # contains source code, Dockerfile and docker-compose.yml

Development server:

To get a development server up and running, run the following commands:

npm install
npm start

Run Docker Image:

(Note: Make sure that the following commands are run in the directory where Dockerfile is present)

Run the following commands to build and test the application as docker images

docker build -t <dockerImageName>:<tag> .
docker run -it -d -p 3000:8000 --env-file ./.env --name inji-verify-dev <dockerImageName>:<tag>

To build the Docker image locally, use the following command. Ensure you are in the directory containing the Dockerfile:

docker build -t inji-verify:local

Stop and delete the docker containers using the following commands:

docker stop inji-verify-dev
docker rm inji-verify-dev

Run Using Docker Compose:

(Note: Make sure that the following commands are run in the directory where docker-compose.yml file is present)

Use the above image <dockerImageName>:<tag> in the docker-compose.yml file and run the following commands to run as docker compose:

$ docker-compose up -d # if docker compose is installed as a standalone command.
$ docker compose up -d # if docker compose is installed as a plugin to docker command

To stop the application, run the following command:

$ docker-compose down # if docker compose is installed as a standalone command.
$ docker compose down # if docker compose is installed as a plugin to docker command

Once started, the application is accessible at http://localhost:3000.

Demo Setup:

This section helps to quickly get started with a demo of the Inji Verify application

Once the repository is cloned, move into the inji-verify repository directory. Choose one of the branches that are currently available for the demo:

release branches:

• release-0.8.x
• release-0.9.x

tags :

• v0.9.0
• v0.8.1
• v0.8.0

active branches:

• master
• develop

cd ./inji-verify # repository folder
git checkout branchName/tagname # choose from any of the above branches

To start the application, run the following commands:

$ cd ./inji-verify # source code folder
$ docker-compose up -d # if docker compose is installed as a standalone command.
$ docker compose up -d # if docker compose is installed as a plugin to docker command

The application is now accessible at http://localhost:3000.

Once the demo is done, cleanup using the following command:

$ docker-compose down # if docker compose is installed as a standalone command.
$ docker compose down # if docker compose is installed as a plugin to docker command

Troubleshoot:

This section contains some common problems that could occur during the setup and steps to resolve then:

Issue with starting docker compose:

no configuration file provided: not found

or

Can't find a suitable configuration file in this directory or any
parent. Are you in the right directory?

Supported filenames: docker-compose.yml, docker-compose.yaml, compose.yml, compose.yaml

Solution:

Make sure that you are in the right directory inji-verify/inji-verify and the docker-compose.yml file is present in this directory.

Check using ls command in ubuntu terminal or dir command in windows command prompt for the contents of the current directory

Issue with ports:

Error response from daemon: Ports are not available: exposing port TCP 0.0.0.0:3000 -> 0.0.0.0:0: listen tcp 0.0.0.0:80: bind: An attempt was made to access a socket in a way forbidden by its access permissions.

Solution:

Try updating the port in the docker-compose.yml file from 3000:80 to <other_port>:80 and try again

Issue with building docker image:

ERROR: failed to solve: failed to read dockerfile: no such file or directory

Solution:

Make sure that you are in the right directory inji-verify/inji-verify and the Dockerfile is present in this directory.

Check using ls command in ubuntu terminal or dir command in windows command prompt for the contents of the current directory

Issue with docker engine:

docker engine/socket not available

Solution:

In Windows: Start/Restart Docker desktop application

In Ubuntu: Run the following command to make sure that the docker service is running

sudo systemctl restart docker.service
