Instances are a great starting point for taking advantage of self service features and spinning up both VMs and containers. In Morpheus it may be advisable to cover the definition of a few terms used within the application so as to reduce confusion. These concepts are also covered in greater detail in the Provisioning Concepts section.
A set of containers or virtual machines that can correlate to a single horizontally-scalable entity or a service suite, like a database. It is important to note that an Instance can contain one or more containers/VMs depending on the Instance type and configuration.
Typically a docker container provisioned via a Morpheus Docker host.
- Virtual Machine
A virtualized compute server provisioned onto various hypervisor hosts.
The top of the main Instances page shows overall statistics for the listed Instances, including count, status, and resource utilization. You can search for Instances by name, or filter by group, instance type, or category.
Instances listed are determined by group access and role permissions. When filtered to show Instances of “All Statuses”, any Instances which are in a state of pending removal due to a delayed delete policy in place are not shown under this filter. Instead you must filter for “Pending Removal” to see these Instances and prevent deletion, if desired.
The Instance list contains important information about each instance, including the instance name, environment tag, instance type icon, IP address and port info, Instance version, the number of virtual machines or containers in the instance, the group the instance is in, and the cloud or clouds the instance is in.
The Instance catalog is the one-stop shop for selecting items to be provisioned and pieced together. It contains not only basic container and VM options but also tailored services for SQL databases, NoSQL databases, cache stores, message busses, web servers, and even full-fledged apps. The list contains a lot of items to choose from and they are represented to the user based on what provisioning engines are enabled and integrated in the Morpheus environment.
To get started, simply click the + Add button in the upper right of the Provisioning > Instances section. A modal will display allowing the catalog to be searched. Once an item is selected it is just a matter of following the steps through the wizard.
The Instance catalog can be customized via role-based access control (RBAC) thereby restricting access to non-sanctioned catalog items, as well as added to via the Library section. It is completely customizable.
The next step will ask for a Group and Cloud to be selected. The Group is an abstract representation that can contain multiple cloud integrations. Clouds can be in multiple Groups and Groups are also useful for using RBAC to restrict provisioning access and set retainment policies. If the environment is new and these do not yet exist, it may be advisable to refer to one of our starter guides, such as the guide on getting started with Morpheus and VMware. The wizard continues by allowing us to choose a name for the Instance as well as an environment.
Currently the Environment option is mostly useful for presenting the user with informative metadata around the Instance when coming back to it later.
Moving on, it is now time to configure the Instance. Depending on the Instance Configuration that is chosen, fields will change. This can include cloud-specific fields (i.e. Datastore for VMware or Network). There will also be options like setting an initial user account. Some of these fields are optional and will be represented as such.
Configuration options provided in this screen are very powerful. An example is MySQL where a Master/Slave or Master/Master layout can be selected. These configurations will automatically deploy two MySQL VMs or containers and link them together to provide replication. These types of configurations exist for a wide range of Instance types and are optimized for high performance and scale. It is even possible to provision entire sharded MongoDB clusters.
One last step before the Instance can be provisioned is the Automation step. This wizard step may or may not appear depending on the capabilities of the Instance type or previous configurations in the account. It is here one can easily select a post-provisioning workflow to run (see more on Tasks and Workflows elsewhere in Morpheus documentation), assign a load balancer, or even configure the backup job that gets created.
Now that the steps are completed for provisioning the selected Instance type, simply review your selections and complete. The Instance will automatically show up in the Instances list and its provisioning state will be represented. Depending on what was provisioned this step can range from seconds to minutes (typically a container configuration will be rather quick if the Instance type has previously been provisioned before).
Converting Discovered Resources to Managed Instances¶
When creating new cloud integrations (or updating existing ones), users may opt for Morpheus to onboard any existing resources that currently reside in the Cloud. For example, these may be virtual machines that exist on vCenter hosts prior to integration with Morpheus, EC2 instances pre-existing on an Amazon AWS account, or virtual machines that are running on a KVM host. With the Add/Edit Cloud modal open, mark INVENTORY EXISTING INSTANCES for Morpheus to automatically onboard these resources. Not only will Morpheus inventory these instances at the time the cloud is integrated (or updated), it will also continue to poll the target cloud every five minutes (by default) for newly added or removed servers. Users can see these discovered servers by looking in Infrastructure > Compute. Depending on the type of resource, it may appear on the Virtual Machines tab, the Containers tab, or another tab. Additionally, we can see a list of discovered servers on Cloud detail pages (Infrastructure > Clouds > Selected Cloud). Just click on the tabs for VMs, Containers or Hosts tab. Discovered resources will be indicated as such whereas containers which are associated with a managed Instance will be marked as a “Managed”.
Additionally, Morpheus allows users to convert discovered resources into managed Instances. Begin from the server detail page (Infrastructure > Compute > Virtual Machines > selected machine) and from the ACTIONS menu select “Convert to Managed”. At this point, we must make a number of selections:
Assign to the primary Tenant or one of the Subtenants
Select a Group (this dropdown contains a filtered list of Groups which the associated Cloud is in)
Username and password for a seeded account
Opt to install Morpheus Agent or not (for more on Morpheus Agent, click here)
Select the Instance Type which should be associated with the new Instance containing this VM
Select a version number for the Instance (such as 20.04 for a basic Ubuntu Instance)
Select a Layout, Instance Types often have multiple Layout configurations
Identify the operating system
Select a Plan (this dropdown contains a filtered list of plans which correlate to the size of the VM)
Finally, click EXECUTE. Once this process is completed, the server will be indicated as “Managed” in the servers list. Additionally, a new Instance will appear on the Instances List page (Provisioning > Instances). We can now work with it in the same way we can work with any other Instance, such as by adding it to an App or expanding the Instance horizontally with added nodes.
The instance detail page is where you can view and fully manage an instance. To get to an instance detail page, navigate to provisioning, instances, and click on an instance. Please note instance details and actions differ between instance types and user permissions.
There are several sections within an Instance page that provide useful capabilities to the user.
Stats and status information
Track deployment history for instance types that support deployments or manually kick off a deployment (only visible for instance types that support deployments)
Some instance types support custom configuration settings (i.e. mysql presents the my.ini)
Useful for configuring security groups and access to the instance.
Quick summary of the monitoring system and all checks that were configured to test the state of the instance
Quick backup dashboard. Useful for viewing historical backups as well as kicking off new ones.
View all aggregated logs from the containers or VM’s representing the instance.
View the environment variables presented to the instances or exported by the instances via Apps (more on this in the Apps section). Even see Imported environment variables that may be referenced by the running instance.
For instances that support load balancing and auto scaling. Easily configure auto scaling thresholds and load balancer settings that pertain to a particular instance. When creating a scale schedule for already-provisioned Instances, a timezone selection is not shown because Morpheus automatically detects the timezone configuration of the web browser. “Library: Threshold” Role permission is required on the Tenant and User Role to see the Scale section of the Instance detail.
Access the instance or container via a client-less Console supporting SSH, RDP, VNC, and even hypervisor level remote consoles.
Instance actions allow you to perform numerous management tasks on instances. The actions available depend on the instance type, hypervisor, roles permissions, and instance state.
Edit the Name, Description, Environment, Group, Metadata, Tags, and Owner for the Instance.
Deletes the Instance.
Deleting an Instance will delete the actual VM’s or Containers and cannot be undone, unless a Delayed Removal policy has been applied prior to the Deletion. To delete Instances without deleting associated VM’s, delete the Instances VM record(s) from the Infrastructure section with “Remove Infrastructure” deselected and select “Remove Associated Instances” in the VM delete modal options. This will delete the records in Morpheus but leave the infrastructure in place.
You can change the owner of an instance easily by selecting the edit button and entering a new owner in the corresponding field.
Available options in the Actions dropdown can include:
Puts the VM in a suspended state without shutting down the OS.
- Stop/Start/Restart Service
Stops, Starts or Restarts the service associated with the Instance Type.
- Stop/Start/Restart Server
