cluster-client | Sharing Connection among Multi-Process Nodejs | Socket library

1. scylla-cluster-client.scylla.svc is a k8s resolvable DNS address, so only works from pods hosted on the same cluster (and namespace). You can't use it from the outside
2. kubectl exec runs a command on one of the Scylla pods, so essentially you are running the command on the Scylla node itself and connecting to localhost on that node. In contrast, scylla-cluster-client.scylla.svc is connecting remotely (but within the k8s network)
3. You don't need to use an IP - use the scylla-cluster-client.scylla.svc DNS name. If you want to use IP addresses you can manually resolve the DNS name or read the IP addresses of the Scylla pods using the k8s API - but there's really no reason to do that. If you want to connect from outside the cluster you would need a public service or something like that - basically a k8s managed proxy. In theory you could allow the public pods but that's highly inadvisable.

As stated on wikipedia, the general format of the X-Forwarded-For is:

I have made the following change for UserData which will get latest cfn-init.

mysql@bootstrap needs to be executed on only one node. The other node do a normal start and then it will SST off the first node.

With two nodes you will have trouble getting a quorum and its unworkable as a HA system.

this context, almost certainly. I'm not entirely certain what this context will a function called inside socket.on get, but arrow functions use the lexical this, so that would be one solution.

The data that you're looking for (name of the cluster) is available at GCP level. The name itself is a resource within GKE, not Kubernetes. This means that this specific information is not available using the client-go. So in order to get this data, you can use the Google Cloud Client Libraries for Go, designed to interact with GCP.

As a starting point, you can consult this document.

First you have to download the container package:

memcached limits the key length to 250 bytes. The only way to change that is by modifying memcached.h and recompiling. Of course you cannot recompile your memcached on ElastiCache.

The common pattern is for you to hash (say with SHA1) your keys. Actually, some memcached clients do this for you by default.

Or consider moving to Amazon ElastiCache for Redis, Redis has a max key size of 512MB.

Had the same error when used with react-test-renderer :

TypeError: Cannot read property 'default' of undefined

To fix it, I mocked native-base's Icon component in my jest's setup file:

Deactivate the Plugin iThemes Security or simply delete its folder in wp-content/plugins
