In this article, we will discuss various approaches and techniques for improving Docker image size with layers, including multi-stage builds, using minimal base images, and using base images with pre-installed packages or pre-built binaries. By following these best practices, we can create smaller and more efficient Docker images that are optimized for performance and scalability. The size of Docker images with layers can be improved using a variety of methods as given below. Methods Using minimal base images Using base images with pre-built binaries Using multi-stage builds Using base images with pre-installed packages Let us discuss these methods ... Read More
Introduction By using containerization, we can quickly set up and configure our deployment environments, which helps us save time and resources. With the goal of "write once, deploy anywhere" in mind, containerization can help us streamline the process of deploying modern applications, which can be complex. Finding the layers and layer sizes for Docker images In this article, we will explore how to find the layers and layer sizes for each Docker image. This can be useful for identifying large layers that may be contributing to the overall size of the image, and for determining which layers can be removed ... Read More
Introduction Docker is a powerful tool that allows developers to build, ship, and run applications inside containers. Containers are small, independent executable packages that contain all the components - code, libraries, dependencies, and runtime - that an application requires to function. One of the key features of Docker is the ability to manage and monitor the processes running inside containers. In this article, we will explore how to find Docker container processes and how to use different methods to view and manage them. Prerequisites You will need Docker installed on your computer in order to follow along with this guide. ... Read More
Docker is a widely used tool for developing and managing containerized applications. It enables programmers to combine their applications with their dependencies into small, portable containers that are simple to set up and use on any platform. Directly mounting Network File System (NFS) shares or volumes inside a container using Docker Compose v3 is one practical Docker capability. In this article, we will explore how to use Docker Compose v3 to directly mount an NFS share or volume in a container. Method to directly mount NFS share/volume in the container using Docker Compose v3 Here are some important terms and ... Read More
In this article, we will learn how to write a swift program to find the prime numbers from the array. Prime numbers are those numbers that are only divisible by 1 and itself. Or we can say prime number have only two factors that are 1 and the number itself. For example, 1, 2, 7, 3, 11, 31, etc. So to find the prime numbers from the given array, we individually check each element of the given array is prime or not. Algorithm Step 1 − Create a function. Step 2 − Check if the number is greater than ... Read More
In this article, we will learn how to write a swift program to remove all ‘nil’ elements from the array. Till now we all know that an array can store elements of a single data type. But Swift array can also hold elements of multiple data types. To store multiple data types in the array we use [Any], where [Any] specifies that the address can hold elements of any data types. Similarly an array also contain nil value. Here we use the following methods to remove nil elements from the array. Using compactMap() function Using filter() function ... Read More
In this article, we will learn how to write a swift program to find even numbers from the array. Even number are those number which are completely divisible by 2. For example, 2, 6, 50, 20, etc. Here we use the following methods to find the even numbers from the array. Using for-in loop Using filter() function Method 1: Using for-in loop To find the even numbers from the given array we use for-in loop. Using for-in loop we iterate through each element of the given array and check if the element is even number or not. ... Read More
In this article, we will learn how to write a swift program to fetch elements from an array based on an index. Using array syntax An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. In an array, every element has an index. The array index is start from 0 and goes up to N-1. Here N represent the total number of array elements. To retrieve elements from the array according to their index we can use subscript syntax. ... Read More
Introduction Secure Shell (SSH) is a network protocol that allows secure remote connections between two systems. It is commonly used to access and manage Linux servers remotely. However, one of the problems with using SSH is that your session can be terminated due to downtime or network outages. This can be frustrating, especially if you're working on a long-running task that requires an uninterrupted connection. In this article, we will discuss various methods of keeping an SSH session alive on Linux. Using the ClientAlive Interval Option One way to prevent an SSH session from closing due to inactivity is to ... Read More
In this article, we will learn how to write a swift program to convert set of string to array of string. An array is used to store elements of same data type in an order whereas a set is used to store distinct elements of same data type without any definite order. Now to convert a set of string to an array of string we use the following two methods − Using Array() initializer Using map() function Method 1: Using Array() Initializer To convert a set of string to an array of string we can use Array() initializer. ...
