module.exports = {
token: "yourbottoken",
timeInterval: "0 * * * * *",
userId: 123456789,
targets: [
{
url: "https://example.com/healthcheck",
name: "Server name one",
ip: "33.33.33.224",
},
{
url: "https://example2.com/healthcheck1",
name: "Server name two",
ip: "33.33.33.224",
},
],
};- Run it with
docker-compose up --build -d
For change time interval check node-schedule readme
You can use any working url. I use something like this:
import express from "express";
const app = express();
app.get("/healthcheck", (req, res) => {
const healthcheck = {
uptime: process.uptime(),
message: "OK",
timestamp: Date.now(),
};
try {
res.send(healthcheck);
} catch (e) {
healthcheck.message = e;
res.status(503).send(healthcheck);
}
});
