Docker For Azure Deployment Walkthrough
- 1. Walkthrough of docker swarm mode on azure -> deploying containers (https://docs.docker.com/docker-for-azure/) Standing up the Azure Environmentw/ swarm mode 1) Create an Azure Service Principal (needed to stand up Azure Container Env for ID/secret keys). a) docker run -ti docker4x/create-sp-azure sp-name rg-name rg-region i) Sp-name = deployment name ii) Rg-name = resource-group-name iii) Rg-region = eastus, westus etc. b) End result will give you the AD ServicePrincipal ID/Secret. You’ll need this when setting up the docker swarm env in azure 2) Click the following to begin configuration of azure swarm deployment (https://portal.azure.com/#create/Microsoft.Template/uri/https%3A%2F%2Fblue-sea-697d.quartiers047.workers.dev%3A443%2Fhttps%2Fdownload.do cker.com%2Fazure%2Fstable%2FDocker.tmpl) a) Use the existing ResourceGroup, ServicePrincipal App ID and Secret created in step 1. b) Choose as many master/slave nodes as you want. Demo master = 1, slave = 3 Getting access to nodes 3) Logging into the Master node a) Ssh with tunnelling (if using putty make sure your private key is setup in pageant. b) If using putty: i) Host = docker@<ssh-LB-IP> ii) Connection -> SSH -> Auth -> Allow Agent Forwarding 4) Logging into Slave node a) Enter “cat /etc/resolv.conf” to get the internal domain name b) Enter “docker node ls” to get the swarm node to connect to c) Then enter “ssh <node-name>.<internal-domain-name>”
- 2. Deploying 1) Log into the master node 2) Run one container a) docker service create --name <customName> -p 80:80 nginx 3) Run multiple a) docker service create --name <customName> --replicas <int> -p 80:80 nginx 4) Manually scale container a) docker service scale <service-name>=<int> Deploying Docker Swarm 1) docker stack deploy --compose-file docker-stack.yml vote
