< p > I've recently bought a < a href = "http://www8.hp.com/us/en/products/proliant-servers/product-detail.html?oid=5379860" > HP Proliant Microserver Gen8< / a > to play around with LXC and try new stuff.< / p >
2016-01-31 15:19:29 +01:00
< p > From the 4 Debian machines I had to keep up-to-date, I now have 7, so it became quite time-consumming to manually SSH to each of them whenever an update became available.< / p >
2016-01-31 15:44:13 +01:00
< p > I ended up looking at < a href = "http://www.ansible.com/" > Ansible< / a > to speed up the process and, within an hour, I had a working playbook that updates the debian packages, pip packages and git repos installed on all of my servers with a single command.< / p >
2016-01-31 15:19:29 +01:00
< p > I figured I'd share the playbook I use to update the Debian packages !< / p >
< h2 > The playbook< / h2 >
< p > I modified < a href = "https://gist.github.com/maethor/380676f6b1cec8cc7439" > this gist< / a > to only use apt-get instead of both apt-get and aptitude.< / p >
