Covers the basic data types in Python, describing common scalar types like 'int', 'float', 'str', and 'bool', and their usage in storing data.
Input and Output
Shows how to use 'print' for displaying output and 'input' for getting user input from the console.
Python Definition
A brief explanation of Python as a high-level, interpreted programming language supporting multiple programming paradigms.
Positive Lookbehind
Matches a group of characters that come before the main part of a pattern. Uses (?<=...). Only matches if conditions are met before the main part.
Negative Lookahead
Matches any input string not followed by a specific pattern. Uses (?!pattern). Useful for excluding certain patterns from matches.
Positive Lookahead
Matches a group only if it is followed by another specified pattern. Does not consume matched text. Uses (?=pattern).
Quantifiers
Specify the number of occurrences a character or group can have. Includes *, +, ?, {n}, {n,}, and {n,m}.
Alternation
Allows matching either the pattern before or after it, used to create multiple possible matches within a single regex.
Character Classes
Allow defining a set of characters for matching. Use [] to define characters like [abc], or ranges like [a-z].
Anchors
^ matches the start of a string while $ matches the end. Used to specify where in a line or string you want to match.
Backreferences
Used to match a previously captured group. Reuses part of the matched text in the regex.
Global Search Modifier (/g)
Performs a global search, meaning it matches all occurrences of the pattern in a string.
Dotall Mode (/s)
Allows the period (.) to match newline characters as well, useful for spanning multiple lines.
Multiline Mode (/m)
In multiline mode, ^ and $ match the start and end of each line within a string instead of the entire string.
Unicode Support (/u)
Enables full Unicode matching, including case-insensitivity and word boundaries.
Case-insensitive Matching (/i)
Allows for case-insensitive matching, treating uppercase and lowercase letters equally.
Verbose Mode (/x)
Allows comments and whitespace in the pattern for readability, helpful for complex regex patterns.
Insert Mode - Inserting/Appending Text
Commands to insert or append text at different positions relative to the cursor.
Working With Multiple Files
Commands to edit, switch between, and manage multiple buffers and files.
Search In Multiple Files
Commands for searching patterns across multiple files with navigation options.
Tabs
Commands for managing tabs including opening, switching, and closing tabs.
JetStream - Create New JetStream
Creates a new stream based on the config of another, without copying data. Example usage is `nats stream copy ORDERS ARCHIVE --description "Orders Archive" --subjects ARCHIVE`.
JetStream - Backup/Restore
Enables backup and restore functionality for streams. Example usage includes `nats stream backup ORDERS` and `nats stream restore ORDERS`.
JetStream - Misc
Provides various maintenance commands for streams, such as marking a stream as read-only with `nats stream seal ORDERS` or evicting a stream with `nats stream cluster peer-remove ORDERS nats1.example.net`.
Publish
Allows publishing messages to a destination. For instance, publish 100 random messages with `nats pub destination.subject "{{Random 100 1000}}" --count 100`.
Subscribe
Enables subscribing to messages, for example, subscribing to a queue group with acknowledgment using `nats sub source.subject --queue work --ack`.
JetStream - Page
Facilitates paging through a stream, with commands like `nats stream view ORDERS` and `nats stream view --since 1h`.
JetStream - Purge
Allows purging messages from streams, including deleting up to certain sequences with commands like `nats stream purge ORDERS --seq 1000`.
JetStream - Get Messages
Retrieves and manages specific messages in a stream, such as getting a particular message with `nats stream get ORDERS 12345`.
JetStream - List Streams
Lists available streams with basic info or compatibility with pipes using commands like `nats stream ls`.
Contexts
Manages connection contexts, including creation or updates with `nats context add development --server nats.dev.example.net:4222`, and viewing with `nats context ls`.
Inbox
Guarantees message delivery in the Nats.io inbox feature, ensuring messages are delivered even if the subscriber is temporarily offline.
Viewing pod logs
Use the command 'kubectl logs <pod_name>' to view logs of a specific pod. Utilize the '-f' flag to stream log output and '--timestamps' to add timestamps. Specify a container with '-c <container_name>' if needed.
Checking cluster events
Use 'kubectl get events' to view recent events in the cluster. Provides insights into cluster activities, errors, or evictions. Events can be filtered with '--field-selector' and monitored continuously with '-w'.
Describing a Pod
Use 'kubectl describe pod <pod-name>' to get details on a pod, including configuration and status. Provides image details, volumes, addresses, and conditions.
Monitoring resource utilization
Use 'kubectl top' commands to view CPU and memory usage in resources like pods and nodes. Requires metrics server.
Inspecting logs from pods or containers
Retrieve container logs using 'kubectl logs', specifying pod and container names. Flags '-f' for real-time and '-n' for number of lines can be used.
Analyzing network traffic within the cluster
Use 'kubectl proxy' to connect local and API server, then tools like Wireshark to analyze traffic. Capture packets to troubleshoot network issues.
Checking pod status and health
Use 'kubectl get pods' for pod statuses, 'describe pod <pod-name>' for detailed info, including readiness probes. Verify pod's operational status using this data.
Creating a PersistentVolume
Define and apply a PersistentVolume with YAML specifying configuration details. Bind PVs to pods using labels and selectors.
Defining a StorageClass
Define storage classes in Kubernetes for dynamic provisioning, specifying parameters for different storage types (e.g., SSD, HDD).
Dynamic provisioning of storage
Utilize StorageClass to automatically create volumes as needed, avoiding manual pre-provisioning. Triggers dynamic volume creation.
Using volume expansion
Expand volumes dynamically by modifying PVC's capacity. Requires storage class support for dynamic resizing.
