Introduction

There are two deployment methods.

Setting Up Standalone

• Generate a single Docker container
• Can bind an independent IPv6 address, but requires Docker to be installed with this project's installer and a host IPv6 subnet of at least /112
• Support for x86_64 and ARM architecture servers

Download the Script

Command:

curl -L https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/onedocker.sh -o onedocker.sh && chmod +x onedocker.sh

Example

Supported parameters are as follows:

./onedocker.sh name cpu memory password sshport startport endport <independent_ipv6> <system> <disk>

Currently, the system only supports selecting:

• alpine
• debian
• ubuntu
• almalinux
• rockylinux
• openeuler

with Debian being the default choice.

Disk size can be set only if you previously enabled disk-limit support during Docker installation. If omitted, disk size is unlimited by default.

./onedocker.sh test 1 512 123456 25000 34975 35000 N debian 5

The following is the information for the created example container:

Attribute	Value
Container Name	test
Username for SSH Login	root
Password for SSH Login	123456
Number of CPU Cores	1
Memory Size	512MB
SSH Port	25000
Port Range for Internal and External Mapping	34975 to 35000
Operating System	debian
Whether to bind a separate IPv6 address	N
Disk Size	5G

Related operations

Deleting the test container

docker rm -f test
rm -rf test
ls

Accessing the test container

docker exec -it test /bin/bash

To exit the container, simply execute exit.

Query Information

cat Container_Name(change me)

The output format is

Container_Name SSH_Port Root_Password Number_of_Cores Memory Start_of_Public_Port End_of_Public_Port

The container IPv6 address can only be checked from inside the container; it is not exposed in the default Docker output here.

Batch Deployment

• Run inheritance configuration generation multiple times in bulk.
• When generating multiple instances, it is recommended to execute within a screen session to avoid SSH connection interruptions.
• Support for x86_64 and ARM architecture servers

Command:

curl -L https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/create_docker.sh -o create_docker.sh && chmod +x create_docker.sh && bash create_docker.sh

Querying information on batch openings

cat dclog

The output format is

Container_Name SSH_Port Root_Password Number_of_Cores Memory Start_of_Public_Port End_of_Public_Port Disk_Size

Each line corresponds to one container. The IPv6 address can only be checked from inside that container.

Uninstall all Docker containers and images

The following cleanup command keeps ndpresponder to avoid breaking IPv6 configuration.

docker ps -a --format '{{.Names}}' | grep -vE '^ndpresponder' | xargs -r docker rm -f
docker images --format '{{.Repository}}:{{.Tag}} {{.ID}}' | grep -v 'ndpresponder' | awk '{print $2}' | xargs -r docker rmi
rm -rf dclog test
ls

Update all commands related to the above one-click scripts

Delete the original configuration script

rm -rf /usr/local/bin/ssh_sh.sh
rm -rf /usr/local/bin/ssh_bash.sh
rm -rf /usr/local/bin/check-dns.sh
rm -rf /root/ssh_sh.sh
rm -rf /root/ssh_bash.sh
rm -rf /root/onedocker.sh
rm -rf /root/create_docker.sh

Download back the relevant configuration scripts for the new version

curl -sSL https://raw.githubusercontent.com/oneclickvirt/docker/main/extra_scripts/check-dns.sh -o /usr/local/bin/check-dns.sh && chmod +x /usr/local/bin/check-dns.sh
curl -sSL https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/config.sh -o /usr/local/bin/config.sh && chmod +x /usr/local/bin/config.sh
curl -sSL https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/ssh_bash.sh -o /usr/local/bin/ssh_bash.sh && chmod +x /usr/local/bin/ssh_bash.sh

curl -sSL https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/onedocker.sh -o /root/onedocker.sh && chmod +x /root/onedocker.sh
curl -sSL https://raw.githubusercontent.com/oneclickvirt/docker/main/scripts/create_docker.sh -o /root/create_docker.sh && chmod +x /root/create_docker.sh

Start all containers after host reboot

By default, containers are not configured for auto-restart after host reboot. Run the following command to start all stopped containers.

docker start $(docker ps -aq)

Start SSH service for all containers after host reboot

Because these containers do not run a full init system by default, SSH may not auto-start. Use the following command to start SSH in all running containers.

container_ids=$(docker ps -q)
for container_id in $container_ids
do
    docker exec -it $container_id bash -c "service ssh start"
    docker exec -it $container_id bash -c "service sshd restart"
    docker exec -it $container_id sh -c "service ssh start"
    docker exec -it $container_id sh -c "/usr/sbin/sshd"
done
