What is 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝 and how does docker 🐬 work?
When we use the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐂𝐋𝐈 to create a container, the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐜𝐥𝐢𝐞𝐧𝐭 changes the command into a 𝐑𝐄𝐒𝐓𝐟𝐮𝐥 𝐀𝐏𝐈. This API is then sent to the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐃𝐚𝐞𝐦𝐨𝐧.
The Docker Daemon first checks if the image is already on the local system. If it's not, it downloads the image from the 𝐃𝐨𝐜𝐤𝐞𝐫 𝐫𝐞𝐠𝐢𝐬𝐭𝐫𝐲.
Once the image is downloaded,
It calls 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝 to start the container. Containerd converts the downloaded image into an 𝐎𝐂𝐈-𝐜𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐭 𝐛𝐮𝐧𝐝𝐥𝐞.
This bundle is then passed to 𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫𝐝-𝐬𝐡𝐢𝐦, which calls 𝐫𝐮𝐧𝐂 to start the container and handle 𝐧𝐚𝐦𝐞𝐬𝐩𝐚𝐜𝐞𝐬 and 𝐜𝐠𝐫𝐨𝐮𝐩𝐬.
✅ 𝐑𝐮𝐧𝐂 uses 𝐥𝐢𝐛𝐜𝐨𝐧𝐭𝐚𝐢𝐧𝐞𝐫 to interact with the Linux kernel and manage containers.
