Managing IP Pools

You can monitor a set of available free and busy IP addresses in the IP pool section. It includes two separate lists with internal and external IP addresses (can be found upon expanding the IP pool option at the left-hand JCA menu).

Click on the Internal / External option to see the list of internal / external IP addresses correspondingly, with their statuses, domains and regions they are assigned to.

In the shown table you can find the following information:
  • IP address - the list of all IPs in a pool
  • Status - indicates whether the IP is in use (the red busy label) or is available for users (the green free label)
  • Domain - displays name of the environment, which includes a container with the corresponding address bound. Clicking on a particular domain will redirect you to the Cluster > Environments section, where the detailed information on the chosen environment will be shown.
  • Region - physical location of the hardware a particular IP belongs to

Using the upper tool panel, you can filter this list in order to show only those IP addresses, that Starts / Ends with the stated IP (specified within the blank input field next to the filtering drop-down list) or have Any match with it. In addition, you can select a particular Status (i.e. all, busy and free) and/or a Region for the addresses to be separated out.

Once all of the required parameters are stated, just click on Search to apply filtering. Subsequently, you can select Clear to remove the conditions and show the whole list of IPs.

Tip: Also, you can click on a particular domain name (with an assigned address) for viewing information on the corresponding Environment within the same-named section to the right.

Here, you can find the following environment data, divided into columns:
  • Name - name of the chosen environment with the expandable list of all instances it includes and deployed contexts
  • ID - unique ID value for each instance
  • IP address - all bound IP’s, both internal and external (if are any) ones
  • Hardware node - name and IP address of the hardware node, where a particular instance is located

Select a separate container within this area if you want to migrate it to another hardware node.

In addition, you are able to perform the following operations in the External IP pool section:

Migrate a Container

You can migrate any node with busy IP (regardless of whether it’s internal or external address). For that, choose the required IP address from the list and navigate to the opened Environment section at the right. Then select the necessary container and click the Migrate button above.

In the opened dialog box, specify the destination hardware Node using the drop-down list and click Migrate.

Add External IP Range

If you run out of external IP addresses for your cluster nodes, you can add a new IP range in the following way:

1. Select the Add IP range button at the toolbar.

2. In the opened Add IP range dialog frame, type the start and end IPs, tick at least one region within the list below (for these addresses to be available at) and click Add.

Tip: You are also able to add a new range of Public IPs from a new subnet.

3. As a result, a new IP range will appear in the list.

Remove External IP Address

In case an IP address is no longer needed, select it with the left-hand check-box and press the Remove button at the toolbar above.

Note that you cannot delete an IP address, which is in use (i.e. has the busy status).

After the deletion, this address will disappear from the list and all of the information about it will be removed from Jelastic DB.
