I have a simple javascript file that uses selenium to launch Chrome, open some website, and collect some data from that website. Now, I want to put that file and run it inside a Docker container.
To do this I wrote the following Dockerfile:
FROM alpine
RUN apk add --update nodejs npm chromium
COPY . /src
WORKDIR /src
RUN npm install -g chromedriver
RUN npm install
ENTRYPOINT ["node", "index.js"]
The image builds with no errors, but when I attempt to run the container from it I get:
/src/node_modules/selenium-webdriver/remote/index.js:248
reject(Error(e.message))
^
Error: Server terminated early with status 1
at /src/node_modules/selenium-webdriver/remote/index.js:248:24
at processTicksAndRejections (node:internal/process/task_queues:96:5)
There's only one dependency for my index.js file - "selenium-webdriver": "^4.1.1", and the file itself looks like this:
index.js
const {Builder, By} = require('selenium-webdriver');
(async function example() {
let driver = await new Builder().forBrowser('chrome').build();
try {
// Navigate to Url
await driver.get('https://www.example.com');
// Get all the elements available with tag 'p'
let elements = await driver.findElements(By.css('p'));
for(let e of elements) {
console.log(await e.getText());
}
}
finally {
await driver.quit();
}
})();
What am I doing wrong? How can I make the container run successfully?
