Topologies

A Minimal Fresh topology with minimum 3 Worker Managers, minimum 2 worker nodes, one DTR with local storage and another as replica would look like the following

Patches and pull requests

Patches can be submitted as GitHub pull requests. If using GitHub please make sure your branch applies to the current master as a 'fast forward' merge (i.e. without creating a merge commit). Use the git rebase command to update your branch to the current master if necessary.

Pre-Req and or Optional Usage of Operational Management Suite

OMS Setup is optional and the OMS Workspace Id and OMS Workspace Key can either be kept blank or populated post the steps below.

Create a free account for MS Azure Operational Management Suite with workspaceName

  • Provide a Name for the OMS Workspace.

  • Link your Subscription to the OMS Portal.

  • Depending upon the region, a Resource Group would be created in the Sunscription like "mms-weu" for "West Europe" and the named OMS Workspace with portal details etc. would be created in the Resource Group.

  • Logon to the OMS Workspace and Go to -> Settings -> "Connected Sources" -> "Linux Servers" -> Obtain the Workspace ID like ba1e3f33-648d-40a1-9c70-3d8920834669 and the "Primary and/or Secondary Key" like xkifyDr2s4L964a/Skq58ItA/M1aMnmumxmgdYliYcC2IPHBPphJgmPQrKsukSXGWtbrgkV2j1nHmU0j8I8vVQ==

  • Add The solutions "Agent Health", "Activity Log Analytics" and "Container" Solutions from the "Solutions Gallery" of the OMS Portal of the workspace.

  • While Deploying the DDC Template just the WorkspaceID and the Key are to be mentioned and all will be registered including all containers in any nodes of the DDC auto cluster.

  • Then one can login to https://OMSWorkspaceName.portal.mms.microsoft.com and check all containers running for Docker DataCenter and use Log Analytics and if Required perform automated backups using the corresponding Solutions for OMS.

  • Or if the OMS Workspace and the Machines are in the same subscription, one can just connect the Linux Node sources manually to the OMS Workspace as Data Sources

  • New nodes to be added to the cluster as worker needs to follow the Docker Instructions for OMS manually.

  • All Docker Engines in this Azure DDC autocluster(s) are automatically instrumented via ExecStart and Specific DOCKER_OPTIONS to share metric with the OMS Workspace during deployment as in the picture below.

Create ACR
  • Create Dockerized new Azure cli
  • $ docker run -dti -v ${HOME}:/home/azureuser --restart=always --name=azure-cli-python azuresdk/azure-cli-python
  • Login to Azure from the cli docker instance
  • $ docker exec -ti azure-cli-python bash -c "az login && bash"
  • Please view output below. Subscription Id, Tenant Id and names are representational.
  • To sign in, use a web browser to open the page https://aka.ms/devicelogin and enter the code XXXXX to authenticate.

Note on Docker EE and Docker CE for Azure

Presently Docker is using the docker4x repository for entirely private images with dockerized small footprint go apps for catering to standard design of Docker CE and Docker EE for Public Cloud. The following are the last ones for Azure including the ones used for Docker Azure EE (DDC) and Docker CE. The base system service stack of Docker for CE and EE can be easily obtained via any standard monitoring like OMS or names obtained via docker search docker4x --limit 100|grep azure
