Artifactory – Upload artifact through command line

Jenkins works well with Artifactory and the built artifact will be upload to the Artifactory repository automatically.

One day, i found that the artifact is built but it is not uploaded. The Linux server doesn’t have the desktop interface so i couldn’t upload the artifact through browser. An alternative way is to use the curl command to post the artifact to the repository.

curl -X POST <target url> --data <artifact>

 

Example:

curl -X POST http://localhost:8081/artifactory/dev-snapshot-local/eureka-v0.0.1.tar.gz --data eureka-v0.0.1.tar.gz

 

Done =)

Django – Schedule django-admin command using django-chronograph

Previously we talked about setting up some custom command in a Django project.

 

I would like to run the custom command in a regular interval. I could use Linux cronjob but it’s hard to manage and check the run history. It would be great if i could setup and manage these scheduled commands on the Django web portal.

django-chronograph, written by wnielson, is a Python Package which allows us to schedule any django-admin command through the web interface. It works well with the UTC timezone but if you have set the TIME_ZONE in your Django project setting.py, there would be time discrepancy.

For more detail about the bug, you can refer to the Issue #36 – Job doesn’t follow the Django’s TIME_ZONE setting.

Ubuntu – Install Monit

Monit is a opensource monitoring tool on Unix system. The simplest use case would be restarting your service if there is failure.

On Ubuntu, simply run apt-get to install Monit.

sudo apt-get install monit

 

The Monit folder is at /etc/monit. Before you can read anything from Monit, create the /etc/monit/conf.d/monit.conf in order to setup the Monit web interface.

set httpd port 2812 and
  use address localhost
  allow localhost

Housekeeping Puppet Master

Yesterday i used a Puppet master as an example to talk about purging old files on Linux.

Of course we can setup a cron job and run the shell command daily for housekeeping. But as we are using Puppet, we don’t we do that thru Puppet manifest?

tidy { 'puppet::reports':
  path => '/var/lib/puppet/reports',
  matches => '*.yaml',
  age => '14d',
  backup => false,
  recurse => true,
  rmdirs => false,
  type => 'ctime',
}

 

The above tidy type will delete those .yaml which is older than 14 days.

Done =)

Linux – Delete files which are older than N days

One day i found that the Puppet master is running out of space and then i realize that there is a lot of run reports in YAML format located @ /var/lib/puppet/reports. I want to delete the old reports for releasing the disk space.

So i move to the /var/lib/puppet/reports directory and execute the following line to recursively remove any .yaml which is older than 14 days.

find $d -type f -name \*.yaml -mtime "+14" -exec rm -f {} \;

 

A few years ago i had a post about a housekeeping shell script which is quite similar to the above approach.

Done =)
