Create NCache Containers for Linux

Once you have set your Docker environment, you can now proceed to create containers for NCache Server images hosted on Docker Hub for Enterprise and Professional editions.

Pull NCache Docker Image

Execute the following command to pull the NCache Enterprise Server Docker Image for Linux.

docker pull alachisoft/ncache:enterprise-server-linux-latest

Refer to our Docker Hub repository to check out which other Docker images we provide.

Configure Custom Network

Before proceeding to create containers for NCache in Linux, you need to configure a custom network. By default, without the usage of a custom network, Docker assigns containers dynamic IP addresses on a container or host restart. A custom network will help assign your NCache containers static IP addresses.

Important

It is highly recommended to use static IPs for each container as all future connections will take place using this IP. These IPs should exist in the IP range specified in the custom network created.

NCache client-server connections are IP-based, and if this IP keeps on changing, the connection will break. So, we need to assign static IP addresses to our NCache containers. The following docker network create command creates a custom network called nbrg that contains subnet 172.19.0.0/16 and specifies the gateway as 172.19.0.1. You can change the values according to your environment.

docker network create --subnet=172.19.0.0/16 --gateway=172.19.0.1 nbrg

Create Container from Image

Once you have pulled the NCache Docker image and created your custom network, you can create containers that host NCache and use them as cache servers. The container can be created with either the docker run or docker create command, the difference being docker run starts the container when it is created.

Note

Note that while creating containers, the image specified should exist locally. If not, the image is then fetched from Docker Hub if the name of the repository is specified.

The following commands create the containers named ncache-ent-server-01 and ncache-ent-server-02 using the custom network nbrg and shipped image alachisoft/ncache:enterprise-server-linux-latest.

sudo docker run --name ncache-ent-server-01 --net nbrg --ip 172.19.0.11 -itd alachisoft/ncache:enterprise-server-linux-latest

sudo docker run --name ncache-ent-server-02 --net nbrg --ip=172.19.0.12 -itd alachisoft/ncache:enterprise-server-linux-latest
