Introducing mailing in crontab-ui

Now crontab-ui has option to send mails after execution of jobs along with output and errors attached as text files. This internally uses nodemailer and all the options available through nodemailer are available here.

Defaults

To change the default transporter and mail config you can modify config/mailconfig.js.

var transporterStr = 'smtps://user%40gmail.com:password@smtp.gmail.com';

var mailOptions = {
    from: '"Fred Foo 👥" <foo@blurdybloop.com>', // sender address
    to: 'bar@blurdybloop.com, baz@blurdybloop.com', // list of receivers
    subject: 'Job Test#21 Executed ✔', // Subject line
    text: 'Test#21 results attached 🐴', // plaintext body
    html: '<b>Test#21 🐴</b> results attached' // html body
};

Troubleshooting

Make sure that you have node at /usr/local/bin/node else you need to create a softlink like this

ln -s [location of node] /usr/local/bin/node

Setting up crontab-ui on raspberry pi

In this tutorial I will show you how to setup crontab-ui on raspberry pi.

Step 1

Find your architecture

uname -a
Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux

Note that it is ARMv7. Download and extract latest node.

wget https://nodejs.org/dist/v7.7.2/node-v7.7.2-linux-armv7l.tar.xz
tar xz node-v7.7.2-linux-armv7l.tar.xz
sudo mv node-v7.7.2-linux-armv7l /opt/node

Step 2

Remove old nodejs if it is already installed and add the latest node to the $PATH

sudo apt-get purge nodejs
echo 'export PATH=$PATH:/opt/node/bin' > ~/.bashrc
source ~/.bashrc

Step 3

Install crontab-ui and pm2. And start crontab-ui.

npm install -g crontab-ui
npm install -g pm2
pm2 start crontab-ui

Now your crontab-ui must be running. Visit http://localhost:8000 on your browser to see if it is working.

Step 4 (Optional)

In order to be able access crontab-ui from outside, you have to forward the port 8000. Install nginx and configure.

sudo apt-get install nginx
sudo vi /etc/nginx/sites-available/default

Paste the following lines in the file:

server {
    listen 8001;

    server_name localhost;

    location / {
        proxy_pass http://localhost:8000;
    }
}

Restart nginx

sudo service nginx restart

Now, crontab-ui must be accessible from outside through port 8001. So, to access crontab-ui, go to

<ip address of pi>:8001

You can also setup http authentication by following this.

Crontab UI: easy and safe way to manage your crontab files

Editing the plain text crontab is error prone for managing jobs, e.g., adding jobs, deleting jobs, or pausing jobs. A small mistake can easily bring down all the jobs and might cost you a lot of time. With Crontab UI, it is very easy to manage crontab.

Here are the key features of Crontab UI:

1. Easy Setup
2. Safe adding, deleting or pausing jobs. Easy to maintain hundreds of jobs.
3. Backup your crontabs.
4. Export crontab and deploy on other machines without much hassle.
5. Error log support

Setup

You have to setup crontab-ui on all the machines on which you want to manage crontab. Note that while running Crontab UI, you have to be on the same user as that of the crontab.

npm install crontab-ui
crontab-ui

Adding, deleting, pausing and resuming jobs.

Once setup Crontab UI provides you with a web interface using which you can manage all the jobs without much hassle.

Backup and restore crontab

Keep backups of your crontab in case you mess up.

Export and import crontab on multiple instances of Crontab UI.

If you want to run the same jobs on multiple machines simply export from one instance and import the same on the other. No SSH, No copy paste!

But make sure to take a backup before importing.

See when the job is going to run next.

Separate error log support for every job

These are some of the things I am planning to add in the future

1. Run jobs as different user in one place.

2. Profiling jobs.

3. Importing from existing crontab file.

Contribute

Fork Crontab UI and contribute to it. Pull requests are encouraged.
