Deploying a Single Container

Get your container online ASAP by deploying a single container quickly into an environment.

Cycle provides a completely UI based form to deploy individual containers. It provides a quick and easy way to get a container online without much configuration. Once the container is created, you will be able to modify any part of it's configuration to a fine degree. To get started, follow these steps:

  1. Give your container a name, and provide initial information about the deployment.
  2. Select or import a new image.
  3. Configure Public Access including hostname.
  4. Verify everything is correct and deploy.

Step 1: Basic Information

Container Name

The name of a container is for your purposes only, and doesn't affect any other aspect of the container. However, on this form, Cycle will automatically prefill the hostname of the container with a formatted version of the name for convenience. You are free to change the hostname without affecting the name.

Give your container a descriptive name

Initial Instances

The instance slider tells Cycle exactly how many copies of the container you want to run when it starts. Based on the deployment tags you set, Cycle will automatically balance the instances across your cloud.

Set instance count

Set tags

If you want to be descriptive about which servers this container will be deployed to use tags.

Any Tags - Instances will deploy to any server with at least one of the tags listed.

All Tags - Instances will only be deployed to a server that has every tag listed here.

Set the tags for you instances

Step 2: Select an Image

Possibly the most important part of deploying a container is selecting WHICH container to deploy. Using the image selector, you can choose from a previously imported image, or import a new one on the spot from various sources, including Docker Hub.

  1. Choose how you want to select your image, either an existing image, or import a new one. If you choose existing, skip to step 4.
    Choose either an existing image, or import a new one from within the form.
  2. Cycle does not store your credentials for your private registry or repository. You will need to provide them every time you import that image.
    Using the tabs on the left, select the source you wish to import from. At this time, you can import from either Docker Hub, or a private Docker Registry.

    Docker Hub

    Typing in the "Image Name" box will automatically search hub.docker.com as you type, returning images along with their description and rating. Select your image from the list (or enter a custom one), then set the tag in the tag field. By default Cycle will import the 'latest' tag. You may also provide custom authorization by selecting the "Use Auth" checkbox. Enter your username and password into the respective fields.

    Docker Registry

    If you choose to import from a Docker Registry, the process is the same, except in the URL field you will need to enter the custom url the registry is hosted on. For example, if your image name isimages.website.com/myimage:latest, you would enter images.example.com into the URL field. It's recommended to host your own Docker Registry on Cycle for extra security instead of using the public Docker Hub option.
    Importing an image from Docker Hub.
  3. Wait for the image to import. When complete, your image will be available from the "Image" dropdown menu.
  4. Select your image from the list.

Configure Volumes

Some container images may specify volumes (persistent data storage). Cycle will automatically detect these and ask you to configure them.

Volumes are created for each instance, so if you configure a 1GB volume for your container, but deploy 3 instances of that container to a box, they will use 3GB of storage.
  • Path - The path is automatically determined by the image, and cannot be changed.
  • Type - At this time, "Local" is the only available option, which means the volume will be created on the local server the instance is deployed to. In the near future, we will have more storage options available, such as SAN.
  • Max Size - Containers will grow to the max size set. Since this is a limit and not an allocation, it is possible that the volume won't have enough data to grow to the max size.
Configuring volumes

Step 3: Configure The Network

Hostname

The hostname is the string that all other containers within the same environment can refer to it by. It must be lowercase, and only contain letters, numbers, and hyphens.

Public Network

There are three types of network privilege a container can have:

  • Disabled - Public internet access is completely disabled for this container. It may only communicate with other containers within the same environment. This is ideal for sensitive things, such as databases.
  • Egress Only - The container may initiate connections over the internet, but all incoming connections will be blocked. This is ideal for things that require fetching data from the web, but do not need to respond to inbound requests, such as web scrapers.
  • Enabled - The container is able to both start and accept connections over the internet. This is a must for websites, APIs, and other services where clients may not be known ahead of time.

Advanced Options

TLS/SSL Certificates

This option is only required for NON-HTTP/HTTPS based services you with to secure with TLS, such as a database cluster. You will be responsible for serving the certificates from your container. Cycle utilizes Let's Encrypt to generate and renew TLS certificates. For more information on securing HTTP/HTTPS services with TLS, see here.

Choose how you would like Cycle to handle your certs

Step 4: Finalize

Verify everything is correct in the deployment summary box on the right, then click the "Create Container" button, located on the bottom right side of the form. All of these options will be fully configurable after creation as well, so if you make a mistake you can easily correct it before starting the container.
