Updating and autostart

After the platform is installed and running, use the steps below to update it to new image versions and to make it start automatically when the server boots.

• Update the software

  To update the software, stop the containers in /opt/vadtelnewweb:

  bash

  docker-compose down

  Then go to /var/lib/unicloud and do the following.

  • Stop the unicloud service:
  bash

  sudo service unicloud stop

  • Shut down the containers:
  bash

  docker-compose down

  Copy and unpack the new compressed image files:

  bash

  gunzip vadtel-nginx-latest.tar.gz
  gunzip vadtel-app-latest.tar.gz
  gunzip anytelemetry-latest.tar.gz
  gunzip pgbouncer-latest.tar.gz
  gunzip vadteljsondaemon-latest.tar.gz
  gunzip logrotate-latest.tar.gz
  gunzip postgres-15.1-alpine.tar.gz
  gunzip redis-6.0.16-alpine.tar.gz
  gunzip vector-latest.tar.gz

  Load the images into Docker:

  bash

  docker load -i vadtel-nginx-latest.tar
  docker load -i vadtel-app-latest.tar
  docker load -i anytelemetry-latest.tar
  docker load -i pgbouncer-latest.tar
  docker load -i vadteljsondaemon-latest.tar
  docker load -i logrotate-latest.tar
  docker load -i postgres-15.1-alpine.tar
  docker load -i redis-6.0.16-alpine.tar
  docker load -i vector-latest.tar.gz

  Check that the images are available:

  bash

  docker images

  If the images loaded without errors, run the following commands from the /var/lib/unicloud folder:

  shell

  sudo service unicloud start
  docker-compose up -d

  Then go to /opt/vadtelnewweb and start the application:

  shell

  docker-compose up -d

  Check the running containers:

  bash

  docker ps

• Configure autostart

  Create, edit, or copy the /etc/docker/daemon.json configuration file and add the following (adjust the values if necessary):

  daemon.json

  {
    "log-driver": "json-file",
    "log-opts": {
      "max-size": "50m",
      "max-file": "3"
    }
  }

  Next, create an autostart script for the application. You need a docker-compose-vadtel.service file with the contents below, where WorkingDirectory is the path to docker-compose.yml.

  Open the file:

  shell

  nano /etc/systemd/system/docker-compose-vadtel.service

  Add the following contents:

  docker-compose-vadtel.service

  [Unit]
  Description=Docker Compose vadtel Application Service
  Requires=docker.service
  After=docker.service
  StartLimitIntervalSec=60
  
  [Service]
  WorkingDirectory=/opt/vadtelnewweb
  ExecStart=/usr/bin/docker-compose up
  ExecStop=/usr/bin/docker-compose down
  TimeoutStartSec=0
  Restart=on-failure
  StartLimitBurst=3
  
  [Install]
  WantedBy=multi-user.target

  code

  To enable the autostart script from /etc/systemd/system/, run:

  shell

  sudo systemctl enable docker-compose-vadtel
