Application Containers

Objective

This guide explains how to use Application Containers on Ruk-Com Cloud PaaS, with ordered procedures and practical verification points.

Before you begin

• Sign in with an account permitted to manage the relevant environment.
• Confirm the target environment, region and resources before saving changes.
• Create a backup or rollback plan before changing a production system.

Container application It is a relatively new container type. It provides microservices, which are centralized to running a single process within a container. Container applications thus promote the creation of immutable and non-permanent infrastructure. To update the application or service All containers will be recreated. Including necessary adjustments from the appropriate images. The container is then provisioned to replace the running container instance.

Complexity in the beginning as well asLack of proper separationAnd the incompatibility of container applications with certain technologies such as Java and Database running on them greatly affects the speed at which container applications can be deployed. Developers must make significant methodological adjustments to ensure that additional technology and functionality can correctly run within container applications.

Moreover, application containers are a stateless method in which data cannot be saved internally. Therefore, the data is permanently stored outside the system. However, developers say stateless containers will lead to deployments being an outdated architectural design. This is the best way to do stateless operations for containers.

Today, there are many tools available to complement container applications. It is used to provide convenient services. As a result, developers benefit from highly specialized containerized application units without the disadvantages and complex management.

Container applications have evolved in many ways, such as Docker, CRI-O, Containerd, etc. Now Ruk-Com Cloud's platform providesautomatic deploymentatFast server coverageandProcess stateless data/providing storage toolssuch as sessions, logs, configs, and more to be conveniently used with container applications.

However, some applications and technologies may still experience issues while migrating to application containers. (Due to the scarcity of separation, the lack of status and a single process requirement), which is especially relevant for complex containerized application orchestration tools like Kubernetes in the event of migration issues. This container system is considered a more suitable alternative for moving containers.
