Attach an iex session to running elixir/OTP process
I have an elixir/OTP application running in production, that was started with mix phoenix.server. It has several processes that hold state. One of these is a stash, implemented as Agent, that currently have a state that I would like to manually change, without stopping the whole application. Once I'm in a iex session inside the application it will be trivial, but I don't know if such option is eve
【k8s】NodeとPodの関係 - Qiita
お題 勘違いしていた表題について。 NodeとPodの関係 k8sでの「Node」は、GKEでは「GCEインスタンス」になる。 GKEでクラスタ作成時に「クラスタサイズ」という形で確保する「Node」の数を決める。 で、以下のように、たしかに「Node」が３つあることがわかる。 $ kubectl get nodes NAME STATUS ROLES AGE VERSION gke-my-cluster-1-min-default-pool-ea807978-8d2t Ready <none> 12h v1.9.7-gke.6 gke-my-cluster-1-min-default-pool-ea807978-hpqc Ready <none> 10h v1.9.7-gke.6 gke-my-cluster-1-min-default-pool-ea807978-ss7p Ready
Nodes
NodesKubernetes runs your workload by placing containers into Pods to run on Nodes. A node may be a virtual or physical machine, depending on the cluster. Each node is managed by the control plane and contains the services necessary to run Pods. Typically you have several nodes in a cluster; in a learning or resource-limited environment, you might have only one node. The components on a node inclu
Node – Elixir v1.6.5
Elixir v1.6.5 Node View Source Functions related to VM nodes. Some of the functions in this module are inlined by the compiler, similar to functions in the Kernel module and they are explicitly marked in their docs as “inlined by the compiler”. For more information about inlined functions, check out the Kernel module. Link to this section Summary
Parsing JSON with Unix tools
I'm trying to parse JSON returned from a curl request, like so: curl 'http://twitter.com/users/username.json' | sed -e 's/[{}]/''/g' | awk -v k="text" '{n=split($0,a,","); for (i=1; i<=n; i++) print a[i]}' The above splits the JSON into fields, for example: % ... "geo_enabled":false "friends_count":245 "profile_text_color":"000000" "status":"in_reply_to_screen_name":null "source":"web" "truncated"
ExMessenger Exercise: Understanding Nodes in Elixir | AkitaOnRails.com
I was exercising through this 2014's old blog post by Drew Kerrigan where he builds a bare bones, command line-based, chat application, with a client that send messages and commands to a server. This is Elixir pre-1.0, and because it's an exercise I refactored the original code and merged the server (ex_messenger) and client (ex_messenger_client) projects into an Elixir Umbrella project and you ca
