![]() Most of the time we connect to Docker running on our local machine, but you can also connect to Docker on a different machine too. There are two ways to deploy it on the remote host: 1. How to connect to remote docker engine using DOCKER_HOST environment variable Using the DOCKER_HOST environment variable to set up the target engine.ĭOCKER_HOST environmental variable is used to set the url to a docker engine which can be local or remote. Let’s see what happens when we list containers locally and on a remote host. Show all the local containers using this command:Ģ.The DOCKER_HOST variable has different syntax, including tcp: // to connect to an export port and unix: /// to connect to a local socket. The easiest method to configure securely is to use ssh as we did docker run -dP nginxģ. Showing all the running containers on the instance.Ī single CLI can have multiple contexts. Each context contains all of the endpoint and security information needed to manage a different cluster or node. This command is used for adding the key temporarily to the ssh agent:Ģ.This command makes it easy to configure these contexts and switch between them. The simple way to see what a context looks like is to view the default context: This shows a single context called “default”. It’s configured to talk to a Swarm cluster through the local /var/run/docker.sock Unix socket.ģ. This command used for create the docker context:ĭocker context create docker-machine –docker “host=ssh: And again list our context to see that is used this command:ĥ. Note that if we list the containers, we see only the container running on the local docker engine as we haven’t switched our context:Ħ. ![]() ![]() verify if the context has been switched using: we can change our context with the use command:ħ. Now open the new terminal and login into remote server using this commands. Using this command you can pull any images from Docker Hub and you can run this images on your instance. Use Docker Compose to build an image and run a multi-container application locally.Ĭlone application source code from GitHub.This last step verify that my connection is established on local.Push the application image to your container registry.Bring up the application in Azure Container InstancesĪzure CLI - You must have the Azure CLI installed on your local computer.If you need to install or upgrade, see Install the Azure CLI.ĭocker Desktop - You must use Docker Desktop version 2.3.0.5 or later, available for Windows or macOS. Or install the Docker ACI Integration CLI for Linux.īefore you create your container registry, you need a resource group to deploy it to. In the following example, a resource group named myResourceGroup is created in the eastus region: az group create -name myResourceGroup -location eastus A resource group is a logical collection into which all Azure resources are deployed and managed.Ĭreate a resource group with the az group create command. Refund requests can be initiated by sending emails to the DevLabs Alliance team at or Refund request usually takes 3-4 working days to get approved by Finance and then 10-15 working days to get the payment back into the source account of the learner.Once you've created the resource group, create an Azure container registry with the az acr create command. If a cancellation is done by a learner within 7 days (or less) of the start of the batch or after attending a maximum of 2 classes, 25% of the total paid fee will be deducted and the remaining amount will be refunded to the learner. If a cancellation is done by an attendee, 7 days (or more) before the batch begins, a total of 10% of the total paid fee will be deducted and the remaining amount will be refunded to the learner. If we cancel an event, 100 percent of training/course fees will be refunded to the learner. For refund conditions, please refer to the “Refund” section below.įor Refund(applicable for IVLT and Classroom training) We may need to postpone/cancel an event because of many reasons, such as insufficient enrollments, instructor unavailability, or force majeure events (like floods, earthquakes, political instability, etc). However, the learner can choose to join another batch of the same training/course after discussing with DevLabs Alliance management.įor refund conditions, please refer to the “Refund” section below. Refund/Money back does not apply in any other condition, except the batch is cancelled by DevLabs Alliance due to instructor unavailability insufficient enrollments, or forced measures(like floods, earthquakes, national/global pandemic, political instability, etc.). You are requested to raise the refund request within 7 days of the beginning of the first batch in which you are eligible to attend. For Virtual Instructor-Led (IVLT) training:
