As a DevOps Engineer, you must be aware of 𝐃𝐨𝐜𝐤𝐞𝐫𝐟𝐢𝐥𝐞 𝐁𝐞𝐬𝐭 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞𝐬:


🔍 Use only and only official and verified images as base image.

🔍 Use light weight docker images for base image like alpine linux image distribution.

🔍 Use docker image version instead of using latest version.

🔍 Install only required packages and softwares into Docker Image.

🔍 Do not have multiple layers of RUN instructions in a Dockerfile, instead have single RUN instruction to install all necessary packages into a docker image using && operator.

🔍 When Dockerfile contains too many layers, try to use multi stage docker file.

🔍 Use .dockerignore file to exclude unnecessary files and directories from docker image in order to reduce docker image size.

🔍 Do not use root user to start docker container, use non root user with least privileges.

🔍 Once docker image is built, make sure docker image is scanned before pushing to Docker Registry.

How to Track Changes Inside Your Docker 🐬 Containers 🚀

If you are struggling to pinpoint file changes inside your Docker containers then try out the powerful "docker container diff" command.

➡️ docker diff allows us to quickly identify all added, modified, or deleted files within a specific container since its creation or last start.

With just one command, we can:

➡️ Track changes for smooth deployments
➡️ Understand the impact of recent modifications
➡️ Troubleshoot issues by detecting root causes
➡️ Audit for unauthorized or unexpected alterations

🖥 Checkout the detailed blog with an example: https://lnkd.in/gx_gWC8N

Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. Below is a an overview of the Prometheus architecture:

🏮 Components:
🖥 Prometheus Server:
- Core for collecting, storing, and querying time-series data.
- It’s pull-based and scrapes metrics from targets at regular intervals.
- Stores data in a local time-series database.
❤️ Metrics (Targets/Exporters):
- Apps or services expose metrics.
- Prometheus scrapes metrics from these targets.
📶 Data Model:
- Time-series data with metric names and labels.
- Example: `http_requests_total{method="GET", status="200"}`.
⚠️ PromQL:
- Query language for time-series data.
- Allows filtering, grouping, and math operations on metrics.
⚠️ Alertmanager:
- Handles alerts from Prometheus.
- Manages notifications and integrates with third-party channels.
☁️ Storage:
- Uses local on-disk storage.
- Data retention policies.
- Data is organized in blocks and compacted over time.

🏮 Workflow:
🌐 Configuration:
- Targets and scrape intervals defined in Prometheus config files.
- Relabeling allows modifying or filtering metrics before storage.
📚 Scraping:
- Prometheus Server scrapes metrics from configured targets.
- Targets expose metrics typically at /metrics endpoint.
☁️ Storage:
- Scraped metrics stored in the local time-series database.
- Data organized by metric name and labels.
📚 Querying:
- Users utilize PromQL to query and analyze stored metrics.
- Grafana or Prometheus's UI visualizes query results.
⚠️ Alerting:
- Prometheus evaluates alerting rules based on queries.
- Alerts sent to Alertmanager if conditions are met.
⚠️ Alertmanager Handling:
- Alertmanager receives alerts and manages their lifecycle.
- Handles deduplication, grouping, and sends notifications to configured channels.

⚠️ As a DevOps engineer, understanding Splunk commands is essential for effective log analysis and monitoring.

Here are some commonly used Splunk commands:

1. search: The primary command for searching data in Splunk. Use it to retrieve events based on specific criteria.

2. index: Specifies the index from which to retrieve data. You can filter data by index using this command.

3. source: Filters events based on the source of the data (e.g., log files, network streams).

4. sourcetype: Filters events based on the type of data source (e.g., Apache logs, Windows Event Logs).

5. eval: Creates calculated fields or modifies existing fields. Useful for creating custom fields or transforming data.

6. stats: Aggregates and summarizes data. You can use it to calculate counts, averages, and other statistics.

7. timechart: Generates time-based charts and visualizations. Useful for trend analysis and identifying patterns over time.

8. rex: Extracts fields using regular expressions. Helpful when dealing with unstructured data.

9. dedup: Removes duplicate events based on specified fields.

10. transaction: Groups related events into transactions. Useful for analyzing multi-step processes.

11. top: Identifies the top values for a specific field (e.g., top IP addresses, top error codes).

12. lookup: Enriches events by joining them with external lookup tables (e.g., mapping IP addresses to geolocation data).

Remember that these commands are just a starting point. Depending on your use case, you might need to explore additional commands and features. Happy Splunking! 🚀🔍

Docker 🐬 Container Lifecycle Phases 🚀

Understanding the Docker Container Lifecycle is crucial for efficient container management.

Containers have different states throughout their lifecycle. There are mainly five states that a container can be in during its lifecycle:

🔢. Creation
🔢. Running
🔢. Paused
🔢. Stopped
🔢. Deleted

From creation to deletion, each stage has specific commands and actions. It's important to know what each stage represents and when a container enters each state.
