Labor day long weekend completely messed up my calendar as an addition to random personal obligations. It provided me with no way to focus on anything specific. However to keep my blog going I’ll try to summarize shortly what
happened this week around me in terms of technologies.
Kubernetes meetup at Hootsuite headquarters was pretty good –
listened to Kelsey Hightower and watched live demo of project Envoy.
Other talk was around persistent storage and containers
given by Gordon Klok from PaxAutoma
The topic is still highly controversial for me as it doesn’t make a lot of
sense to have persistent data when your application is Elastic Cloud Native API
driven container system.
It all inspired me to play with Kubernetes on my local
Windows system. Project MiniKube worked as a charm (after I moved to 0.21
version as 0.22 had some file permission issues). The best manual on running Minikube on Windows
10 or 7 is here
After playing with it for awhile I came up to realization
that GCP is another equal issue for my experiments (since I still have over US$400
in credits).
Another completely separate thing I was working this week on
is nawk – my customer’s security department dumping windows logs to linux
machine and than querying them using Linux basic tools. My linux console drove
me crazy as copy/paste were working weird. So I ended up copying logs back to
windows machine and using Cygwin64 which has gawk instead of nawk but also
allows me to pipe to linux native operators such as sort, uniq and grep!
My task was to provide count of all machines
that had over 10 failed login attempts during August. Logs were enormous (as
we are talking of 25K+ users) but the command returns results under 5 minutes
mark – pretty impressive.
gawk -v pat="2017\t4625" '$0 ~ pat' userlog.2017-09-07 | gawk -F" " '{print $4, $17}' | sort | uniq -c | sort -nr
And lastly few interesting articles to absorb:
- Follow up on VMware PKS announcement last week and how different pieces go away and come together
- The most intriguing picture I saw for awhile – Market share of Public Cloud providers in this blog also copied it in here
- Vision of VMware CEO - interesting read
- Messosphere adds support for Kubernetes
- Sober view on automation and orchestration hype - very enjoyable read with a lot of references
