Docker Container SSH Access
Since Docker containers don’t have the embedded GUI for their management, the most common way to take the full control over such an instance is connecting to it under the SSH protocol and perform any desired operations inside using the corresponding terminal commands.
that with Jelastic the majority of the required configurations can be performed directly through the dashboard without the necessity to use SSH, thanks to the following tools:
In addition, you can leverage the Jelastic-dedicated CLI client, which provides the advanced remote management for all types of environments and nodes and allows to automate your app’s lifecycle via scripts.
SSH connection to a container can be established in two ways:
through the Jelastic SSH Gateway as for any other environment. The flow will be the following:
or, if you don’t want to use SSH keys, you need to attach the public IP address to the required node and perform the next steps:
- open your terminal emulator
- enter the ssh [username]@[hostname] string, where the username is your login, and hostname is the Public IP address (you receive these credentials via email everytime a new Docker® container is created or added to the environment)
- specify the requested password (can be found in the email also)
Once you’ve entered your Docker container, you can perform any required configurations, thanks to the full root permissions granted.
In case you’ve forgotten your container’s credentials or lost/deleted the appropriate email, you can restore them at any time - simply choose the Reset password option within the expandable Additional list (the gear icon) for the necessary node (or set of them):
As a result, you’ll receive a new password via email and can use it for operating your Docker container(s).
