[[Gotify]] is developed in [[GO]], which creates single binary executables with no dependencies. It is therefore best practice if we copy or move the executable to a system accessible directory as per best practices. ```CLI mkdir /etc/gotify ``` ```CLI cp gotify-linux-amd64 /etc/gotify/gotify ``` or ```CLI mv gotify-linux-amd64 /etc/gotify/gotify ``` only owner can read/write, anyone can execute (see [[Debian#chmod|permissions]]) ```CLI chmod -R 711 /etc/gotify ``` ```CLI wget -O /etc/gotify/config.example.yml https://raw.githubusercontent.com/gotify/server/master/config.example.yml ``` create log directory as per service file reference ```CLI mkdir /var/log/gotify ``` # Concept The [[Gotify]] server receives messages from applications, which can then be read by clients (logged-in users). A user must be bound to an application in order to be able to see messages from that application. # Configuration > [!cli]+ <code class="g-code">nano /etc/gotify/config.yml</code> > >```YAML server: keepaliveperiodseconds: 0 # use GO default (15s) listenaddr: "" # bind on all addresses port: 80 # http server port number database: dialect: sqlite3 # mariadb and postgresql are also supported connection: /etc/gotify/data/gotify.db # will be created on first use passstrength: 10 # the bcrypt password strength (higher = better but also slower) uploadedimagesdir: /etc/gotify/data/images # will be created if it does not exist pluginsdir: /etc/gotify/data/plugins # leave empty to disable plugins registration: false # enable/disable registrations (uncertain of its functionality) >``` > # Initial Login Start the server: <code class="g-code">/etc/gotify/gotify</code> - run the server in interactive mode, with real-time message exchange displayed in the console Access the [[webUI]] from any browser: <code class="o-code">http://192.168.0.222</code> - assuming default port number was not changed in `config.yml`. ![[gotify-login-0.png]] Change the admin password; read the [first login](https://gotify.net/docs/first-login) suggestions. ![[gotify-login-1.png]] # USERS Users are required in order to see messages from applications. A user with administrative rights will have full access to create/delete users. > ***Only the user who created the application is able to see its messages.*** You can create a single user who is named after an application, or you can create a user who is a person, who will then have to be associated with several applications. > ***Only an admin can manage (create/delete) users*** ## Admin view ![[gotify-users-0.png]] ![[gotify-users-1.png]] ## User view > ***Only admins can manage and therefore view users.*** # APPS ## Admin view > ***An admin cannot view applications created by other users.*** ## User view ![[gotify-apps-0.png]] Custom application images can be uploaded with a maximum suggested size of 512px. Larger the 512px images are not rescaled and therefore uploading large images is not useful (see [image optimisation](https://gotify.net/docs/optimize-images) for more detail). ![[gotify-apps-1.png]] # CLIENTS A client is any application which has successfully logged into the [[Gotify]] server. The application can be a browser session (the [[webUI]]) or the [[Gotify]] [[Android]] app. You can revoke access to the server (e.g if your phone is lost) by deleting the client. ## Admin view ![[gotify-clients-0.png]] ## User view ![[gotify-clients-1.png]] # Start on Boot > [!cli]+ <code class="g-code">nano /etc/systemd/system/gotify.service</code> > >```BASH >[Unit] >Description=Gotify Server >Requires=network.target >After=network.target >Documentation=https://gotify.net/docs/systemd > >[Service] >Type=simple >User=root >WorkingDirectory=/etc/gotify/data >ExecStart=/etc/gotify/gotify >StandardOutput=append:/var/log/gotify/gotify.log >StandardError=append:/var/log/gotify/gotify-error.log >Restart=always >RestartSec=3 > >[Install] ># installs a hook to use this unit file when the system boots or shuts down >WantedBy=multi-user.target >``` > > Alternatively, create the service file in any location you choose (e.g. `/opt/gotify/gotify.service`) and then link to `/etc/systemd/system`: > ```CLI > ln -s /opt/gotify/gotify.service /etc/systemd/system/gotify.service > ``` start server on boot ```CLI systemctl enable gotify ``` ```CLI reboot ``` ensure server started with no errors ```CLI systemctl status gotify ``` reload server, whenever `gotify.service` changes ```CLI systemctl daemon-reload ``` reload server, whenever `config.yml` changes ```CLI systemctl restart gotify ``` # Send Message To test everything works we will send a message to the app we created. In our example we have created an app named `Home Assistant` which has been assigned the token `ANh.Ae1RQCznlqv`. ## Use `CURL` ```CLI curl "http://192.168.0.222/message?token=ANh.Ae1RQCznlqv" -F "title=HA test message" -F "message=test message sent to Gotify App named Home Assistant" -F "priority=5" ``` ![[gotify-message-0.png]] ## Use [[Home Assistant]] ### Text Message (unformatted) > [!cli]+ <code class="g-code">configuration.yaml</code> > add the following lines >```YAML >notify: > # a named notification service is required for every HA user who should receive notifications > - name: gotify_admin # name the service > platform: rest > resource: http://192.168.0.222/message # replace with your IPv4 > # resource: http://gotify.domain.tld/message # replace with your domain name > method: POST > # method: POST_JSON # required for markdown messages > headers: > X-Gotify-Key: ANh.Ae1RQCznlqv # replace the app token value with your gotify app token > # X-Gotify-Key: !secret gotify_admin_key # use a secret instead of the app token value > message_param_name: message > title_param_name: title > target_param_name: target >``` > ![[gotify-ha-restart.png]] To test, go to <span class="fieldname">Developer Tools</span> (service ID is: `notify.gotify_admin`). ![[gotify-ha-message-0.png]] The message can be viewed in the [[Gotify]] [[webUI]] or [[Android]] app. As a reminder you need to be logged in [[Gotify]] with the user credentials used to register the APP (e.g. Home Assistant). ![[gotify-message-0-ha.png]] The example above can be used in any [[HA]] script to send important notifications using the [[Gotify]] notification service. ### Markdown Message (formatted) > [!cli]+ <code class="g-code">configuration.yaml</code> > add the following lines >```YAML >notify: > # a named notification service is required for every HA user who should receive notifications > - name: gotify_admin_md # name the service > platform: rest > resource: http://192.168.0.222/message > method: POST_JSON # required for markdown messages > headers: > X-Gotify-Key: ANh.Ae1RQCznlqv # replace this key with your gotify app token > message_param_name: message > title_param_name: title > target_param_name: target > data: > extras: > client::display: > contentType: "text/markdown" >``` > ![[gotify-ha-restart.png]] ![[gotify-ha-message-1.png]] #### [[webUI]] ![[gotify-message-1-ha.png]] #### [[Android]] ![[gotify-message-2-ha.png]] ![[Gotify#References]] # Follow or Support me -> <a href='https://ko-fi.com/S6S0K9U5Q' target='_blank'><img height='36' style='border:0px;height:36px;float:right; ' src='https://storage.ko-fi.com/cdn/kofi1.png?v=3' border='0' alt='Buy Me a Coffee at ko-fi.com' /></a>
