flask-text-reader

Make text files like logs available for simple remote access via web browser.

Instructions

1. Change the line FILE_PATH=your_file_path_here in the .env file including the path to the file you want to read (the file path is without quotes).
2. Run pip install -r requirements.txt
3. Run bash run_gunicorn or bash run_flask_server for debugging.
4. Your file content will be available on http://your_ip:8050.

Instructions to install as a service

1. Create a unit file ending in .service within the /etc/systemd/system directory to begin: sudo vim /etc/systemd/system/flask-text-reader.service
2. Fill the file with the data describing the service:

[Unit]
Description=Gunicorn instance to serve flask-text-reader
After=network.target

[Service]
User=user_name
WorkingDirectory=/home/user_name/flask-text-reader
Environment="PATH=/home/user_name/flask-text-reader/venv/bin"
EnvironmentFile=/home/user_name/flask-text-reader/.env
ExecStart=/home/user_name/flask-text-reader/venv/bin/gunicorn --bind 0.0.0.0:8050 app:app

[Install]
WantedBy=multi-user.target

3. To ensure proper opeaeration with multiple users, make sure the folder and its contents belongs to a common group of users:
   sudo chgrp -R root flask-text-reader/

Instructions to load the service using Docker

Install Docker

1. First, in order to ensure the downloads are valid, add the GPG key for the official Docker repository to your system:
   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
2. Add the Docker repository to APT sources:
   sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
3. Next, update the package database with the Docker packages from the newly added repo:
   sudo apt-get update
4. Make sure you are about to install from the Docker repo instead of the default Ubuntu 16.04 repo:
   apt-cache policy docker-ce
   You should see output similar to the follow:

docker-ce:
    Candidate: 18.06.1~ce~3-0~ubuntu
    Version table:
        18.06.1~ce~3-0~ubuntu 500
            500 https://download.docker.com/linux/ubuntu xenial/stable amd64 Packages

5. Finally, install Docker:
   sudo apt-get install -y docker-ce
6. Docker should now be installed, the daemon started, and the process enabled to start on boot. Check that it's running:
   sudo systemctl status docker
7. If you want to avoid typing sudo whenever you run the docker command, add your username to the docker group:
   sudo usermod -aG docker ${USER}
8. To apply the new group membership, log out of the server and back in.
9. Afterwards, you can confirm that your user is now added to the docker group by typing:
   id -nG

Install Docker Compose

1. We'll check the current release and if necessary, update it in the command below:
   ssudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
2. Next we'll set the permissions:
   sudo chmod +x /usr/local/bin/docker-compose
3. Then we'll verify that the installation was successful by checking the version:
   docker-compose -v

Execute all the services

docker-compose up -d or docker-compose up -d --build --force-recreate to force recreation of image and container
Check if everything is working via the commands:
docker-compose ps or docker ps
Check the logs of each container via the command:
docker-compose logs container_name
