Error in file docker compose yml service must be a mapping not a nonetype - Исправление ошибок и поиск оптимальных решений проблем

When I ran: COMPOSE_PROJECT_NAME=zk_test docker-compose up, I got error saying

«ERROR: In file ‘./docker-compose.yml’, service must be a mapping, not
a NoneType.».

This is my yml file:

version: '2'

YAML is indentation dependent. This

services:
zoo1:

is a mapping with two keys that both map to null (i.e. None in Python).

Whereas:

services:
   zoo1:

is a mapping nested in a mapping. The key ‘services’ has as value a mapping with key zoo1 (which again has a value null).

Synopsis

When I was building the environment with Docker, I encountered such a build error.

ERROR: In file './docker-compose.yml', service must be a mapping, not a NoneType.

Post a memorandum on how to deal with this error and why it occurred.

Reason for error

Because the indentation is inappropriate. Probably some half-width space is missing.

solution

Suppose you get an error in docker-compose.yml like this.
Example

version: "3"
services:
react-navigation:
  build: ./
  volumes:
    - ./react-navigation/:/usr/src/app
  env_file: .env
  command: bash -c "cd example && yarn start"
  ports:
    - "19000:19000"
    - "19001:19001"
    - "19002:19002"

As a solution, add two half-width spaces under react-navigation and change it like this.

version: "3"
services:
  react-navigation:
    build: ./
    volumes:
      - ./react-navigation/:/usr/src/app
    env_file: .env
    command: bash -c "cd example && yarn start"
    ports:
      - "19000:19000"
      - "19001:19001"
      - "19002:19002"

Afterword

Probably an error that people who have just learned Docker will encounter.
I hope this article will be useful for those people and myself.

Вопрос:

Как я могу решить эту проблему/ошибку?

ОШИБКА: В файле». /docker-compose.yml » служба должна быть отображением, а не типом.

Я не уверен, почему, но я не могу понять мир yml, файл yml находится здесь:

Ответ №1:

Проблема возникает из-за вашего отступа. Проверьте ссылку на docker-compose и синтаксис YAML.

Ваше определение должно выглядеть примерно так:

   1 version: "3.8"
  2 services:
  3   mongodb:
  4     image: mongo
  5     container_name: mongodb
  6     environment:
  7       - MONGO_INITDB_ROOT_USERNAME=microservice
  8       - MONGO_INITDB_ROOT_PASSWORD=A1d2r3i4a5n!
  9     volumes:
 10       - mongodb-data:/data/db
 11     networks:
 12       - mongodb_network
 13     ports:
 14       - 27017:27017
 15     healthcheck:
 16       test: echo 'db.runCommand("ping").ok' | mongo 192.168.254.135:27017/test --quiet
 17       interval: 30s
 18       timeout: 10s
 19       retries: 3
 20     restart: unless-stopped
 21   mongo-express:
 22     image: mongo-express
 23     container_name: mongo-express
 24     environment:
 25       - ME_CONFIG_MONGODB_SERVER=mongodb
 26       - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
 27       - ME_CONFIG_MONGODB_ADMINUSERNAME=microservice
 28       - ME_CONFIG_MONGODB_ADMINPASSWORD=A1d2r3i4a5n!
 29       - ME_CONFIG_BASICAUTH_USERNAME=admin
 30       - ME_CONFIG_BASICAUTH_PASSWORD=admin123
 31     volumes:
 32       - mongodb-data:/data/db
 33     depends_on:
 34       - mongodb
 35     networks:
 36       - mongodb_network
 37     ports:
 38       - 8081:8081
 39     healthcheck:
 40       test:  wget --quiet --tries=3 --spider http://admin:admin123@192.168.254.135:8081 || exit 1
 41       interval: 30s
 42       timeout: 10s
 43       retries: 3
 44     restart: unless-stopped
 45     
 46 volumes:
 47   mongodb-data:
 48
 49 networks:
 50   mongodb_network:

1. последовал за ним, все еще получая ERROR: In file './docker-compose.yml', network 'name' must be a mapping not a string. и после запуска yamllint « 40:81 строка ошибки слишком длинная (92 > 80 символов) (длина строки)«появляется эта ошибка

2. теперь получаем ERROR: The Compose file './docker-compose.yml' is invalid because: services.mongo-express.healthcheck value 'restart' does not match any of the regexes: '^x-' services.mongodb.healthcheck value 'restart' does not match any of the regexes: '^x-'

3. да, restart это не является частью healthcheck сопоставления. Это должны быть сервисы.монго-экспресс.перезапуск. Я отредактирую исходный ответ

4. также networks.mongodb-data.name не является допустимым ключом. Я также отредактировал это в исходном ответе. И вы не указали, где вы монтируете mongodb-data для mongo-express службы. Я поставил /data/db , но, может быть, вам стоит его настроить.

According to the documentation you would have to access the daemon.json where the default bridge is defined and modify the settings you need. It should be something like that by default in your case:{
«bip»: «192.168.99.100/24»,
«fixed-cidr»: «192.168.99.100/25»,
«fixed-cidr-v6»: «2001:db8::/64»,
«mtu»: 1500,
«default-gateway»: «192.168.1.1»,
«default-gateway-v6»: «2001:db8:abcd::89»,
«dns»: [«10.20.1.2″,»10.20.1.3»]
}
You’d have to modify it by ips if they accepted your company’s firewall.Here you can find information about where and how to modify the daemon.js in Windows: https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-docker/configure-docker-daemon

It’s standard shell variable surgery. In this case, the impact will be 127.0.0.1 if the variable DOCKER_HOST_IP Not declared ( empty). Details can be read, for example https://tldp.org/LDP/Bash-Beginners-Guide/html/sect_10_03.html

You don’t have him in public, and it’s also like a full-time judge, it’s in another class, so the ui-freymworth can’t create a copy of it.Take this class to a separate java file and add the retrofit. publicP. S. The library doesn’t have a public class either. But the inflator, in handling the marking file, creates copies of the classes through the reflexia, so this code can be compromised and’ll even work, but it’s best not to do it — you can get a sudden mistake and then you can find a reason for a long time.

Apparently, your ID’s wrong. The yml files use tabs or spaces to delimit blocks similar to python.container_name, volumes, expose,ports, environment and restart are out of kwan.Try to adjust to version: ‘3’
services:
kwan:
image: postgres:11.5
network_mode: bridge
container_name: postgres
volumes:
— postgres-data:/var/lib/postgresql/data
expose:
— 5432
ports:
— 5432:5432
environment:
— POSTGRES_PASSWORD=root
— POSTGRES_USER=postgres
— POSTGRES_DB=root
restart: unless-stopped
backend:
build: .
I think that will solve

How are you simply using one host docker and IIS is not a container/service, the solution would be to get your IIS to access host docker.How docker-created networks are virtual, both default as any other explicitly created, directly only host and the docker themselves told to know it, which prevents, by default, the server hosting the IIS from having access to any docker-managed network, but more easily to the host docker.So, publishing the doors for access by host — —publish , -p or —publish-all , -P, considering that you are using the docker CLI — would be the alternative for you to create the routes on your HTTP server.When using Swarm there are some alternatives like https://docs.docker.com/engine/swarm/ingress/ that facilitates access by resources outside Swarm.

Unfortunately Docker on Windows is not so good, because it has to emulate a linux machine to serve the kernel for the images and only then use the concept of container and batteries, and another thing I noticed is that especially Windows 10 recently is slower than normal for Docker, I say that because I already use Docker over 3 years, as the Docker for believe windows is relatively new and windows 10 is with several problems But summarizing about performance doesn’t have much to do, in this link a discussion was opened to help people with this problem and the developers manage to help, I hope it is useful https://github.com/docker/for-win/issues/1936

I don’t know what kind of image the questioner is making, but if you don’t want to publish the port at least, you shouldn’t be able to access inside the container via the port.

The root cause of this issue was the absence of the relay-log option in the mysql.cnf file (or in this case, due to the docker volume mounts, the docker.cnf file). This lead to the creation and usage of files such as 89726507f176-relay-bin.000002 initially, where 89726507f176 is the host name of the machine (randomly assigned by the docker daemon when an image is created). When the container was stopped, removed and recreated, a new set of files was created and used (e.g. be0c801d95bc-relay-bin.000407) but this caused sync issues.
By explicitly specifying a value for relay-log in the docker.cnf file the container was able to be removed and recreated without problems.
As a side note, I suggested also that there was a problem with the /var/log/mysql directory not being mounted — this is not the case. If however you specify a value of log_bin = /var/log/mysql/mysql-bin.log for example, then this is a requirement. If you do not specify this path, it seems the binary logs are stored locally in /var/lib/mysql which is already mounted outside the container.
My final docker.cnf file is as follows:
[mysqld]
skip-host-cache
skip-name-resolve
bind-address = 0.0.0.0

binlog-ignore-db = mysql
replicate-ignore-db = mysql

log_bin = /var/log/mysql/mysql-bin.log

relay-log = replication-1
server_id = 1

Note: server_id = 2 on the replication slave.
Also note that without the relay-log option the command SHOW MASTER STATUS; returned no results on the master database container.
There is a possible outstanding issue yet which is that by default when you use docker stop it asks the container to terminate (by sending a SIGHUP to the docker entrypoint command) and if it doesn’t terminate within 10 seconds it is forcefully stopped. I need to ensure taht this is given sufficient time to shut down as it could take a little while to sort itself out while under load, possibly resulting in data loss as a result.

In normal situation, mongodb uses always all available memory!!
However, you can limit mongo’s memory using cgroup.
Here is presentation what may help too.

I finally solved it.After being around and helped by the user @JackNavaRow came out the solution.It was as simple as rebooting the system and erasing the volumes.Raise the containers and everything work ok.I’ll leave it here in case someone finds this problem, that doesn’t give him any more spins.EDITADOAnother possible mistake It’s putting inside en la parte de the database name but used the default name.I’d have to put…WORDPRESS_DB_NAME: wordpress
In this example the name is the default but if we had put another name in MYSQL_DATABASE: otro_nombre In case of not specifying in the wp-config as a database wordpress (by default)
