Mounting certificates/CAs for elasticsearch pods in k8s for custom configurations – ECK

Posted on by jlim0930

When you deploy elasticsearch in k8s via ECK by default it takes care of the transport certificates/http certificates/CA creation if you don’t use your own custom ones. Lets say that your cluster is up and running and now you are trying to configure something like SAML/LDAP/OIDC or something else that requires content to be made available to the elasticsearch pod but its a bit sensitive so you need it to be stored as a secret such as CA, certificates, etc. How would you go about doing this? Following example will add a custom certificate authority to be used with your… Continue Reading →

Homemade Electrolyte Ice Cubes to replace tablets

Posted on by jlim0930

I recently started cycling and with the North Texas summer heat decided that I need something more than just water to help me keep hydrated during the summer.  I started by taking nuun tablets and it’s very good but after taking the tablets for a while I noticed that the cost does add up and it does have many unnatural chemicals so I decided to research and come up with my own solution. I dislike coconut flavor, however, coconut water does provide a lot of electrolytes so one formula is based on coconut water and the other ginger.  Also, many… Continue Reading →

is it safe to use epel and rpmforge at the same time ?

Posted on by jlim0930

There are many repositories that you can add onto your RHEL/CENTOS/FEDORA OS to install additional software. full list of repos can be found here http://wiki.centos.org/AdditionalResources/Repositories however is it safe to just add the repos and start installing packages? yes and no. We will configure priorities to setup the repos to keep packages from conflicting. Also you will want to protect the base OS installation so that there is less corruption/conflicts later on. step 1 – install the plugin if its not installed already yum install -y yum-plugin-priorities yum-plugin-protectbase step 2 – setup priorities for *-Base.repo that came with your OS… Continue Reading →

NFS locking down ports for SLES

Posted on by jlim0930

When you run NFS server it will pick random ports for mountd and nlockmgr which can change upon reboot causing nightmares when the nfs is going through a firewall. You can lock these ports down so that its not random anymore edit /etc/sysconfig/nfs and put in the following STATD_PORT=4001 LOCKD_TCPPORT=4002 LOCKD_UDPPORT=4002 MOUNTD_PORT=4003 and restart the nfs services now if you look at the port assignments via rpcinfo you will see that mountd and nlockmgr is locked into a specific port # rpcinfo -p program vers proto   port 100000    2   tcp    111  portmapper 100000    2   udp    111  portmapper 100003    2   udp  … Continue Reading →
