Docker Compose Tips And Tricks For Windows
Use Verified Images
Always use Verified Images it is a best practice which will give you confidence about the authenticity of an Docker Image. Verfied Images are well maintained and easy to understand because all process is well documented. The verified images is updated time to time and fixes bugs and issues related to Images. before using the image you can check on the Dockerhub and use only those images who have official tag and associated with well known organization.
- You can also use Docker inspect command to check the image is signed or not. this is the syntax
docker trust inspect IMAGE[:TAG] [IMAGE[:TAG]...]
Tip : you can check how does Docker Content Trust works and how it verify the images and if you want so you can also use it to verify your own Docker images.
Versioning
Mention the current Docker Compose version in the starting in your Docker File. so there might be less chance of getting the issues with the version. it is the best practice to use latest version and if you want so you can also specify the which O.S you use if you use light weight Os like alpine it will give you advantage and provide efficiency in fetching and pulling the request.
Efficient Catching In Layers
As we know that Time is everything. by following some simple techniques we can save the time, the steps in dockerfile is called as layers in docker compose. and when you run command for building the image so it go through each step. and docker temporarily store the layers which are rebuild. so the next time you rebuild the image so it will not taking too much time and redownload it. when you run the build command. it will speed up the process. The following are the simple techniques you follow for efficient catching:
- Take care of ordering of Layers.
- Use multi stage builds
- Take care of what files you are copying in Docker file
- If you want so can add large files to Dockerignore file i.e nodemodules.
Use Docker Volumes
Docker volumes are very useful feature. by using this feature you can share your data from one container to another container. you can mount your data to another container so if somehow your container are stopped are destroyed so your data is not destroyed with the container. and that’s how you saved your data. if you want so you can also create your custom volumes.
Enviroment Variables
Enviroment variables are the one of the most important factor of Docker File. Make sure to provide the Enviroment variable name according to it’s work which is readable and explain it’s related work and provide default values which will helps in different scenarios.
Docker Compose For Windows: Tips And Tricks
Docker is a powerful Container platform that allows you to create containers where you can run, deploy, and develop applications without worrying about different dependencies, services, and limitations of the operating system. The best part is the isolation of the container so you can use this container on different platforms. Now let’s talk about the ecosystem of Docker.
- Docker Engine: It is the core part of Docker which handles the different functionalities of Docker.
- Docker Compose: It is a tool which is provided by Docker used to maintain multi-container-based applications.
- Docker Hub: it is a cloud platform where all the Docker images are stored similar to Git Hub.
