➡️ The best way to become a DevOps Engineer is to work on practical projects. ➡️ Just watching tutorials or reading ebooks will not make you employable. ➡️ You do not have a job to gain practical exposure. ➡️ Just create a cloud account and spin up a Kubernetes Cluster. ➡️ Deploy a sample application and play with it. ➡️ Then Build CI/CD pipelines using Github Actions and ArgoCD or Flux CD. ✅ Always the best approach to learning a new technology or concept is by using the technology to build something useful. ❤️ Follow for more: @prodevopsguy

🔔 𝗨𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴 𝗲𝘁𝗰𝗱 𝗶𝗻 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 etcd is a consistent, highly available distributed 𝐤𝐞𝐲-𝐯𝐚𝐥𝐮𝐞 𝐬𝐭𝐨𝐫𝐞 using the 𝐑𝐚𝐟𝐭 𝐜𝐨𝐧𝐬𝐞𝐧𝐬𝐮𝐬 𝐚𝐥𝐠𝐨𝐫𝐢𝐭𝐡𝐦 to manage a highly-available replicated log. It provides a reliable way to store data across a cluster of machines, ensuring that data remains consistent even during network partitioning. The data stored in etcd can be accessed by all nodes in a cluster, which can use the stored information for coordination and configuration sharing. ➡️ 𝗛𝗼𝘄 𝗲𝘁𝗰𝗱 𝗪𝗼𝗿𝗸𝘀 etcd uses the 𝐑𝐚𝐟𝐭 𝐜𝐨𝐧𝐬𝐞𝐧𝐬𝐮𝐬 𝐚𝐥𝐠𝐨𝐫𝐢𝐭𝐡𝐦 to manage a highly-available replicated log. It groups instances into clusters, each with a 𝐮𝐧𝐢𝐪𝐮𝐞 𝐈𝐃. Each cluster has a leader who handles client requests and follower instances that replicate the leader's log entries. If a leader fails, the followers hold an election to choose a new leader. The clients send write requests to the leader, which are then appended to its log. The leader subsequently broadcasts these entries to their followers. Once an entry has been safely replicated, the leader applies the entry to its state machine and returns the result of that execution to the client.etcd provides a watch API for applications to monitor changes in keys and directories, providing real-time updates as data changes. ➡️ 𝗨𝘀𝗲 𝗼𝗳 𝗲𝘁𝗰𝗱 𝗶𝗻 𝗞𝘂𝗯𝗲𝗿𝗻𝗲𝘁𝗲𝘀 Kubernetes uses etcd as its primary datastore to manage the cluster state. All cluster data, including the configuration data and the state of workloads running within the cluster, is stored in etcd. It keeps track of nodes, pods, configs, secrets, accounts, roles, and bindings. etcd ensures that even if individual nodes within a Kubernetes cluster fail, the cluster's state remains consistent and highly available. 𝗦𝗼𝗺𝗲 𝗼𝗳 𝘁𝗵𝗲 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗙𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗼𝗳 𝗲𝘁𝗰𝗱 1️⃣. 𝐓𝐫𝐚𝐧𝐬𝐚𝐜𝐭𝐢𝐨𝐧 𝐒𝐮𝐩𝐩𝐨𝐫𝐭:- etcd supports multi-key transactions with conditional flow. This means several operations can be grouped and executed in a single atomic transaction. If the transaction fails at any step, all the changes are rolled back, ensuring data integrity. 2️⃣. 𝐓𝐢𝐦𝐞 𝐭𝐨 𝐋𝐢𝐯𝐞 (𝐓𝐓𝐋) :- etcd provides TTL for keys, which can be used for automatic key expiration. This is particularly useful for use cases like service discovery and leader election, where outdated entries should be automatically removed after a certain period. 3️⃣. 𝐌𝐢𝐫𝐫𝐨𝐫 𝐚𝐧𝐝 𝐏𝐫𝐨𝐱𝐲 𝐌𝐨𝐝𝐞𝐬 :- etcd provides a lease mechanism that can be used to associate keys with a lease. The keys are automatically deleted when the lease expires. This is particularly useful for managing short-lived keys. 4️⃣. 𝐋𝐞𝐚𝐬𝐞 𝐌𝐞𝐜𝐡𝐚𝐧𝐢𝐬𝐦 :- etcd can operate in mirror mode, which mirrors a prefix in the key-value store to another etcd cluster, and in proxy mode, which forwards the etcd API requests to an active etcd cluster. 🔰 𝐅𝐨𝐥𝐥𝐨𝐰 @prodevopsguy 𝐟𝐨𝐫 𝐦𝐨𝐫𝐞 𝐬𝐮𝐜𝐡 𝐜𝐨𝐧𝐭𝐞𝐧𝐭 𝐚𝐫𝐨𝐮𝐧𝐝 𝐜𝐥𝐨𝐮𝐝 & 𝐃𝐞𝐯𝐎𝐩𝐬!!! // 𝐉𝐨𝐢𝐧 𝐟𝐨𝐫 𝐃𝐞𝐯𝐎𝐩𝐬 𝐃𝐎𝐂𝐬: @devopsdocs

🔔 Securing DevOps: Pre-Release Best Practices In the DevOps dynamic landscape, ensuring application security before release is crucial. By implementing proactive measures during the pre-release stage, organizations can mitigate risks and foster a culture of secure software development. The Pre-Release Security Pillars: 1⃣. Code Quality Assurance: Integrating linting and code quality tools into VCS and CI processes to enforce best practices and organizational policies. 2⃣. Static Application Security Testing (SAST): Analyzing source code and binaries to scan for known vulnerabilities, enabling early threat detection and remediation. 3⃣. Secrets Scanning: Ensuring sensitive information like credentials and API keys are not exposed in the codebase, promoting secure handling through dedicated secrets management systems. 4⃣. Software Composition Analysis (SCA): Identifying and scanning third-party libraries and dependencies to mitigate vulnerabilities in underlying open-source components. 5⃣. Container Scanning: Analyzing pre-built container images to identify vulnerabilities in the underlying operating systems and software releases. Modern DevOps platforms like GitLab Secure, JFrog Xray, Snyk, Palo Alto Prisma Cloud, and CrowdStrike offer comprehensive pre-release security tools, enabling organizations to address vulnerabilities and deliver secure applications proactively. 😎 𝐅𝐨𝐥𝐥𝐨𝐰 @prodevopsguy 𝐟𝐨𝐫 𝐦𝐨𝐫𝐞 𝐬𝐮𝐜𝐡 𝐜𝐨𝐧𝐭𝐞𝐧𝐭 𝐚𝐫𝐨𝐮𝐧𝐝 𝐜𝐥𝐨𝐮𝐝 & 𝐃𝐞𝐯𝐎𝐩𝐬!!! // 𝐉𝐨𝐢𝐧 𝐟𝐨𝐫 𝐃𝐞𝐯𝐎𝐩𝐬 𝐃𝐎𝐂𝐬: @devopsdocs
