What is a log drain? Logs are treated as event stream in CF. CF executor with the help of Metron agent send the logs to Loggregator. Doppler is the responsible for forwarding the logs to different log drains i.e. system logs i.e. splunk, paper trail etc... Traffic controller publish the logs to developer terminal and websocket endpoint i.e. Firehose. Nozzles extract the logs form Firehose. How do you create one? By creating user provided service and assigning the log drain path. $ cf create-user-provided-service SERVICE-INSTANCE -l SYSLOG-URL $ cf bind-service YOUR-APP-NAME SERVICE-INSTANCE Why would you use it? To search, filter the logs, debug applications, create reports, find out top exceptions.  What is “Syslog”? System log

What is an application security group (ASG)? What does it do? Application Security Groups (ASGs) are a collections of egress rules that specify the protocols, ports, and IP address ranges where app or task instances send traffic.  The platform sets up rules to filter and log outbound network traffic from app and task instances. ASGs apply to both buildpack-based and Docker-based apps and tasks. Types of ASG's:   Default : public_networks, dns   Staging vs Staging   Platform-wide vs Space Scope Typical ASG's: ASG For access to dns DNS, either public or private public-networks Public networks, excluding IaaS metadata endpoints private-networks Private networks in accordance with  RFC-1918 load-balancers The internal Cloud Foundry load balancer and others internal-proxies Internal proxies internal-databases Internal databases How do you define one? cf create-security-group SECURITY-GROUP PATH-TO-RULES-FILE RULES file eg. [ { ...

1. What is a manifest? What type of file is it? What is its purpose? Manifest is app configuration file which provides declarative way to define app push options. Manifest is a YAML file. Used for deployment of apps in CF. 2. How do you create a manifest? cf  create-app-manifest APP_NAME  [-p pathtofile] - Create an app manifest for an app that has been pushed successfully 3. If I specify a command in a manifest and on the command line what happens? If application build pack need app owner to specify the command to start an application. It overrides the build pack start command. 4. What happens if I don’t specify a deployment option at all? App will be installed with cf defaults i.e. default instances as 1, disk memory as 1GB, RAM as 512MB, default routes etc...

1. What is a service? Can you name some examples? Services are cloud native apps dependencies. Consider S ervice as a factory that delivers service instances. Two types: 1. Managed services Cloud Foundry offers a marketplace of services, from which users can provision reserved resources on-demand. Examples of resources services provide include databases on a shared or dedicated server, or accounts on a SaaS application.  Example: my-sql, rabbitmq, redis etc... 2. User provided services User provided services provides the metadata to connect to the system outside the cloud. These services are not available in market place. This are custom services i.e. connecting to your own external DB or any other service outside the cloud i.e. erp etc.. Command to list the service instances in your space: cf services To see details of particular service cf service SERVICE_INSTANCE_NAME What is the “marketplace”? Does it show all services?  The Pivotal Cloud F...

 How do you access application logs? cf logs APP_NAME cf start APP_NAME To see the logs of particular pcf sub system. cf logs APP_NAME | grep "API\|CELL" To exclude particular logs cf logs APP_NAME | grep -v "API\|CELL" To see application events i.e. start, stop, crash etc... cf events APP_NAME To display all the lines in the Loggregator buffer cf logs APP_NAME --recent  What are the components of the Loggregator system? Loggregator is the next generation system for aggregating and streaming logs and metrics from all of the user apps and system components in a Cloud Foundry deployment. Primary use: 1. Tail/dump logs using CLI.  2. Stream to 3rd party log archive and analysis service 3. Operators and admins can access Loggregator Firehouse, the combined stream from all the apps and metrics data. 4. Operators can deploy nozzle to the firehouse.  A nozzle is a component that monitors the Firehose for specified events and metrics, ...

Kabhi kisi ko mukammal jahan nahi milta, Kahi jami to kahi aasman nahi milta.. Jise bhi dekhiye wo apne aap me gum hai, Zuba mili hai magar hum-zuban nahi milta.. Bujha saka hai bhala kon waqt ke shole, Ye aisi aag hai jisme dhuwa nahi milta.. Tere jahaan me aisa nahi ke pyaar na ho, Jaha ummid ho iski waha nahi milta.. Kabhi kisi ko mukammal jahan nahi milta, Kahi jami to kahi aasman nahi milta..
