How to Install ImageStore on Fedora CoreOS Latest

ImageStore is an application that provides a RESTful API for storing and retrieving images in a simple way. In this tutorial, we will guide you on how to install ImageStore on Fedora CoreOS Latest.

Prerequisites

Before you start with the installation process, make sure you meet these requirements:

A server or virtual machine running Fedora CoreOS Latest
A user account with sudo privileges

Step 1: Install Docker

ImageStore is containerized application and requires Docker installed on the system. Follow these steps to install Docker:

Open a terminal window on your system.
Run the following command to update the package manager:
```
sudo dnf update
```

Add the Docker repository to your system by running the following command:

sudo dnf config-manager --add-repo=https://download.docker.com/linux/fedora/docker-ce.repo

Install Docker by running the following command:

sudo dnf install docker-ce docker-ce-cli containerd.io

Verify the installation by running the following command:
```
docker --version
```
The output is similar to:
```
Docker version 20.10.9, build c2ea9bc
```
Start and enable Docker to run at system boot by running the following command:
```
sudo systemctl enable docker.service
sudo systemctl start docker.service
```

Step 2: Clone the ImageStore Repository

Clone the ImageStore repository from GitHub by running the following command:

git clone https://github.com/gregordr/ImageStore.git

This command will create a new directory called ImageStore that contains the source code of the application.

Step 3: Build the ImageStore Docker Image

Navigate to the ImageStore directory by running the following command:

cd ImageStore

Run the following command to build the ImageStore Docker image:

sudo docker build -t imagestore .

This command will download and install all dependencies required by the application and build the Docker image based on the Dockerfile defined in the repository.

Step 4: Run the ImageStore Container

Run the following command to start the ImageStore container:

sudo docker run -d --name imagestore -p 8080:8080 imagestore

This command will start a container named imagestore and map the port 8080 of the container to the port 8080 of the host.

Step 5: Test the ImageStore Application

The ImageStore application is now running on your system. You can test it by sending a request to the API endpoint:

curl -X POST -H "Content-Type: multipart/form-data" -F "file=@/path/to/image.jpg" http://localhost:8080/store

Replace the /path/to/image.jpg with the path to your image file.

This command will upload the image to the ImageStore and return a JSON object with the URL of the uploaded image.

Conclusion

In this tutorial, we showed you how to install ImageStore on Fedora CoreOS Latest using Docker. You can now use this application to store and retrieve images in a simple way.
