2. Solution

After consulting the information, it is known that it is the cause of the docker0 bridge. To solve the above error problem, the following steps are required.

1. Kill all docker processes

pkill docker 

2. Clear all chains of the nat table

iptables -t nat -F

3. Stop docker default bridge docker0

ifconfig docker0 down

4. Delete the docker0 bridge

brctl delbr docker0

5. Restart the docker service

systemctl restart docker

[Solved] error: password authentication failed for user “postgres”

password authentication failed for user “postgres” with docker

Steps:

    1. 1. run the instruction to create a docker container.

docker run --rm --name test-postgres -p 5432:5432 -e POSTGRES_PASSWORD=pw -d postgres

    1. 2. run the following command in node code to connect to the database:
import pg from 'pg'
const { Pool } = pg
pool = new Pool({
   database: 'postgres',
   user: 'postgres',
   password: 'pw',
   port: 5432
})

The following error is thrown:
error: password authentication failed for user “postgres”

 

Cause analysis

Because Postgres has been installed locally, Postgres is automatically started when the system is started by default. When connecting to the database, the locally installed Postgres service is preferentially connected, so the connection fails.

 

Solution:

Open Window Task Manager, under Services you will see a postgres service running. Right-click to turn off the postgres service, open the Service window and double-click on the postgres service to set the Startup Type to Manual.
then


Other troubleshooting methods

Open the Terminal of the container

  1. Enter the following two commands to see if there is a problem with local host permissions.
    cd var/lib/postgresql/data
    cat pg_hba.conf
  2. To see if the default user is postgres.
    psql -U postgres -x -c "select * from current_user;"
  3. Check the password expiration date. rolvaliduntil no value means no expiration date.
    psql -h 127.0.0.1 -U postgres -d postgres
    SELECT * FROM pg_roles WHERE rolname='postgres';
  4. Try clearing docker’s columns and containers, and restarting docker

[Solved] Docker Error: WSL 2 installation is incomplete.

Problem Description:

This article solves two Docker errors:
1.WSL 2 installation is incomplete.
2.System.InvalidOperationException: Failed to set version to docker-desktop: exit code: -1

After successfully installing Docker today, I ran Docker and the following error occurred:

WSL 2 installation is incomplete.
The WSL 2 Linux kernel is now installed using a separate MSI update package.Please click the link and follow the instructions to install the kernel update:https://aka.ms/wsl2kernel.
Press Restart after installing the Linux kernel.
---

Cause Analysis:

Docker is a tool for packaging, distributing, and deploying applications.
Basically a lightweight virtual machine. There are only things we need in the virtual machine, other superfluous things are necessary.
Important Concepts: Image, Container
Image: Similar to software installation package, it can be quickly spread and installed.
Container: After the software is installed, each software running environment is independent and isolated, which is called a container.
Advantages: It ensures that running on different machines is a consistent operating environment, and there will be no situation where my machine runs normally and your machine runs properly.
When we install docker desktop, he asks if we need to use wsl2 (Windows based subsystem for Linux). If not, we’ll run with a Hyper-V virtual machine. However, this subsystem has better performance compared to virtual machines.

The WAL 2 Linux kernel is now installed using a separate MSI update package.

That’s the problem!

solution:

Let’s go to the system to check whether the Linux subsystem of Windows is enabled. The steps are as follows:
Control Panel -> Programs -> Programs and Features

Check if you have checked here: Enable Windows Subsystem for Linux

If not, we check it, restart the computer, and open Docker.
If you still report WSL 2 installation is incomplete. problem. There is only one reason left:
the version of wsl2 we are using is very old, so it needs to be updated manually. We can download the latest version of wsl2 from Microsoft’s official website according to the prompt, and then open it normally.
Visit the link below to download and install the update:

https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi

If the download is slow, use the Google browser to download, it is easy to use!
Install the latest version of wsl2:

reboot. run.

So far, most of them can run successfully. If not, there is the ultimate trick:
if you report an error at this time System.InvalidOperationException: Failed to set version to docker-desktop: exit code: -1

The error is as follows:

System.InvalidOperationException:
Failed to set version to docker-desktop: exit code: -1

We open cmd as an administrator:
enter:

netsh winsock reset

Execute, 100% solve this problem!

Note: This command should be used with caution. This is to delete the original docker system, which is equivalent to resetting docker-desktop. The images and containers in me are gone. Restarting docker-desktop will regenerate docker-desktop and docker-desktop-data

[Solved] docker Error: bridge docker0 failed: exchange full

Error reported: Bridge docker0 failed: exchange full

the default docker0 bridge only supports 1024 links. If it exceeds 1024, it will report bridge docker0 failed: exchange full

you can remove the restriction by creating another network bridge. When docker run creates a container, you specify our own network bridge. Of course, we only support 1024 network bridges. You can use this method to create unlimited network bridges as long as there is enough memory to create a docker container

1. View Bridge

[[email protected] ~]# docker network ls

3. Create container specified bridge – network

[[email protected] ~]# docker run -m 100m --name zabbix-agent-22001 --network=xinnet -e HOSTNAME="TEST22001" -e ZBX_HOSTNAME="TEST22001" -e ZBX_SERVER_HOST="10.20.9.246" -p 22001:10050 -e ZBX_SERVER_PORT=10051 -d zabbix-agent:4.0.35 
[[email protected] ~]# docker ps -a
CONTAINER ID   IMAGE                 COMMAND                  CREATED          STATUS          PORTS                      NAMES

If – network is not specified, the created containers will be hung on docker0 by default, and the IP of docker0 interface on the local host will be used as the default gateway for all containers

Docker Error: error invoking remote method ‘docker-start-container‘: error: (http code 500) server error –

Docker container cannot be started. An error is reported after startup:

error invoking remote method 'docker-start-container': error: (http code 500) server error - ports are not available: listen tcp 0.0.0.0:3306: bind: an attempt was made to access a socket in a way forbidden by its access permissions.

First restart the computer (host), and then execute it on the command line (or wsl2)

docker ps -a

Check the container ID that cannot be started, and then execute

docker restart Container ID

If it still cannot be started, try to allow the windows (Linux) firewall to pass through the port and make sure it is not blocked by the firewall

[Solved] Docker Error: Failed to connect to bus: Host is down

docker run -itd –privileged –name=apache -v /var/www/html/:/var/www/html/ -p 8888:80 myapache:v1 /usr/sbin/init

Remember, remember

Error content:

The system has not been booted with systemd as init system (PID 1). Can’t operate.
Failed to connect to bus: Host is down

Solution:

docker run -itd    — privileged –name myCentos centos /usr/sbin/init

After creation: use the following command to enter the container

docker exec -it myCentos /bin/bash

Pay special attention to the bold content and don’t forget it

The reason is that/bin/Bash is executed in the first step by default, and systemctl cannot be used because of a bug in docker

Therefore, we use/usr/SBIN/init and — privileged, so that we can use systemctl, but override the default/bin/bash

Therefore, if we want to enter the container, we can no longer use docker attach mycentos

Instead, you can only use   docker exec -it myCentos /bin/bash   Because exec allows us to execute the overridden default command/bin/bash

At the same time -it is also necessary.
