Public network accesses private network Docker container

The Docker container is installed on the host in the local area network, which can only be accessed in the intranet. How can you access the Docker container in the intranet from the external network?

This article describes the specific steps to implement using holer.

1. Preparation 1.1 install and start the Docker container

The default sshd port for the Docker container is 22.

two。 Implement step 2.1 download and extract the holer package

Holer package: holer-xxx.tar.gz

Holer supports a variety of OS system platforms, please select the holer package that matches the local OS type.

2.2 get holer access key information

Apply for your own holer access key on Holer's official website or use access key information publicly available in the open source community.

For example, the holer information you applied for is as follows. Here we take the holer information as an example:

-Holer Client: holerdemo@gmail.comAccess Key: 8866daebe02846t88s166733595fff5d-Internet Address: holer.org:65014Local Address: 127.0.0.1 -2.3 start the holer service

Windows system platform:

Open the CMD console and go to the directory where the executable is located to execute the command:

Holer-windows-xxx.exe-k 8866daebe02846t88s166733595fff5d

Linux or other system platforms:

Execute the command: nohup. / holer-xxx-xxx-k 8866daebe02846t88s166733595fff5d &

2.4 access the mapped public network address

Enter on the ssh client

Hostname: holer.org port number: 65014

Or execute the command: ssh root@holer.org-p 65014

In this way, you can access the Docker container of the intranet from the external network.

2.5 question consultation and help

When you encounter problems in the process of using holer, you can first check the log information printed by the holer console, so that it is easy to find out the specific cause of the problem.
