Preface
When it comes to flow charts, you may think of Visio at the first time. It is undeniable that VIsio is indeed powerful, but the software is paid, and because of its powerful functions, the installation requires a lot of system memory, and it is not possible Cross-platform use. Therefore, today I recommend a more practical flowchart software to you - Draw.io online drawing tool.
In fact, in addition to writing code, drawing is also one of the essential skills for every programmer. We often come into contact with flow charts, architecture diagrams, etc. Moreover, Draw.io combined with the cpolarintranet penetration tool can also add sharing and collaboration functions to improve team work efficiency, so this article will teach you How to deploy the draw.io drawing tool in docker and achieve remote access over the public network.
Docker locally deploys the online drawing tool Draw.io and achieves remote access over the public network
1. Use Docker to deploy draw.io locally
Start docker and run the container
docker run -it --rm --name="draw" -p 8080:8080 -p 8443:8443 jgraph/draw.io
Start a web browser session to http://localhost:8080/?offline=1&https=0 or https://localhost:8443/?offline=1
You can see that draw.io is deployed locally in docker and enters the painting and drawing interface.
2. Install cpolar intranet penetration tool
Above we successfully installed draw.io in docker and successfully accessed it through the LAN. Next we installed the cpolar intranet penetration tool and forwarded the http public network address mapped to the local port through cpolar. We can easily achieve remote access without having to do it ourselves. Register a domain name and purchase a cloud server. The following are the steps to install cpolar
cpolar official website address: https://www.cpolar.com
- Use one-click script installation command
curl -L https://www.cpolar.com/static/downloads/install-release-cpolar.sh | sudo bash
- Add services to the system
sudo systemctl enable cpolar
- Start cpolar service
sudo systemctl start cpolar
After cpolar is successfully installed, access Linux port 9200 on an external browser: [http://LAN ip:9200]. Log in using your cpolar account. After logging in, you can see the cpolar web configuration interface, which is connected to the web management interface. Just configure
3. Configure Draw.io public network access address
Click Tunnel Management - Create Tunnel on the left dashboard to create a Draw.io cpolar public network address tunnel.
- Tunnel name: The name can be customized. Be careful not to duplicate the existing tunnel name.
- Protocol: Select http
- Local address: 8080 (port for LAN access)
- Domain name type: Choose a random domain name for free
- Region: Select China
Click创建
After the tunnel is successfully created, click the status on the left - online tunnel list to view the generated public network access address. There are two access methods, one is http and https
4. Remote access to Draw.io via public network
Use the above cpolar https public network address to access it in the browser of any device, and you can successfully see our Draw.io drawing interface. In this way, a public network address that can be accessed remotely is created. There is no need to purchase a cloud server yourself, that is Can be published to the public network for access.
Since the tunnel created using cpolar above uses a random public network address, it will change randomly within 24 hours, which is not conducive to long-term remote access.
I usually use a fixed second-level subdomain name because I hope that when I send the URL to my colleagues, it will be a fixed and easy-to-remember public address (for example: draw.io.cpolar.cn), which makes it more formal and convenient. Drawing communication and collaboration. Therefore, we can configure a second-level subdomain name for it. This address is a fixed address and will not change randomly [ps: cpolar.cn has been filed]
Note that you need to upgrade the cpolar package to a basic package or above, and the bandwidth corresponding to each package is different. [cpolar.cn has been registered]
Log in to the cpolar official website, click Reserve on the left, select to reserve the second-level subdomain name, set a second-level subdomain name, click Reserve, and copy the reserved second-level subdomain name after the reservation is successful. Level subdomain name
After the reservation is successful, copy the name of the second-level subdomain name that was successfully reserved.
Return to the cpolar web UI management interface, click Tunnel Management - Tunnel List on the left dashboard, find the tunnel you want to configure, and click Edit on the right
Modify the tunnel information and configure the successfully reserved second-level subdomain name into the tunnel.
- Domain name type: Select a second-level subdomain name
- Sub Domain: Fill in the successfully reserved second-level subdomain name
Click更新(Note, click once to update, no need to submit again)
After the update is completed, open the online tunnel list. At this time, you can see that the public network address has changed and the address name has become a fixed second-level subdomain name.
Finally, we use a fixed public network address to access, and we can see that the access is successful. In this way, a fixed and permanent public network address is set.
