The first half of this policy is the default with PM2. Docker will try to restart your container indefinitely until you manually stop ( docker stop) or remove the container ( docker rm -f).
You cannot set a limit to the number of restart attempts with this policy (and with the always policy). after a server restart), only start the container if it was already running before. unless-stopped - Always restart the container, regardless of the exit code.The maximum number of restart attempts in PM2 is configured with the -max-restarts flag or max_restarts option in the configuration file. Whether your app has exited successfully or with an error, PM2 will treat them equally.
DOCKER FACTORY RESET CODE
PM2 doesn't allow you to change the restart behaviour based on the exit code of your application. Optionally, you can pass a limit to the number of restart attempts. on-failure - Only restart the container if it exits with a non-zero code.To achieve the same result in PM2, you would use the -no-autorestart flag in the command line or autorestart: false in your configuration file. This restart policy is the default in Docker. no - Do not automatically restart the container when it exits.There are examples for all possible restart policies at the bottom of this section. The syntax for Docker CLI is -restart= and in Docker Compose, the configuration is nested at the service level with restart. When you start your containerised application, you can choose one of several restart policies provided by Docker.
You get out-of-the-box automatic restarts with PM2, whereas with Docker you have to explicitly enable them. PM2 and Docker have different default settings when it comes to keeping your application online. We'll go over all the restart policies offered by Docker and how they translate to a PM2 based configuration. Your application will be able to handle serious production heavy workloads.
DOCKER FACTORY RESET HOW TO
You will learn how to deploy your application the Docker way, and boost your confidence in deploying to production environments.īy using Docker, you leverage a robust ecosystem that brings standardisation to deployments. In the From PM2 to Docker series, you will see how important features from PM2 translate to their Docker counterparts. Are you having trouble migrating from PM2 to Docker? Or do you want to know if Docker can do the same things as PM2?
