Arukas is a shared hosting service that shares server resources with other customers. Docker container operating with privileged will be able to access other containers on the same host. Also, as with processes running outside the container on the same host, it will be possible to execute the process with the privileges of the host, so it is technically impossible to secure the security of the customer application.

On the control panel, the CMD that can be set for the application is equivalent to the docker run –cmd option.

You can override that Docker image COMMAND(CMD) instruction just by specifying a new CMD. If the image specifies ENTRYPOINT, CMD or COMMAND is added as an argument to ENTRYPOINT.

For character strings that are not interpreted normally unless they are concatenated, it is necessary to enclose the string before and after the string with single quotes (‘). The legend is shown in the table below.

ex. nginx image)

but, Endpoint URL is always the same.
Always-on connection it is supposed to be through the Endpoint.

Endpoint URL is mapped to the first port only.

ex:
port#1: 3456 <= mapped to Endpoint
port#2: 80
port#3: 443

Endpoint need all port opened after endpoint enabled.

EndPoint URL is HTTP backend support. (TCP/UDP not suppoted.)
This is intended to be used in a web server and API Server.

Entity of Endpoint is a load balancer. This will load balance the communication of multiple back-end instance automatically.

All of the instances automatically get rebooted almost every week, The average life span of the ip address and port is one week. Sometimes it changes in one day.

It is good practice to uniquely tag each Docker image. A common way of generating tags is to use the SHA-1 of the commit that it was built from or set the x.y.z format version.

Alternatively, if you prefer to use some fixed tag (Ex. “latest”), you can do so with a dummy environment (ENV) key value in Arukas control panel, which pulls the latest Docker image forcibly and replace the old one.

The Docker.inc official Ubuntu/CentOS images uploaded on Dockerhub does not offer some functionality which can be run as SSH server as a default.

To build some Docker image which can run SSH server, you can refer to the official documentation.

Application is forced to stop within 15 minutes by incorrect setups.

Please make sure that

• your image name and tags are set correctly; otherwise your application might not be up and run.
• a proper port is opened; otherwise your running server may not work as you expect.
• properties specified for your application such as “CMD” and “ENV” are set correctly.
• Your application memory size is sufficient size that? Would be exceeded the memory size of the application bootup, there may be the app does not bootup normally.

※ Arukas supports only the public Docker Image of Docker Hub. Private Docker Images are not supported.
