docker-compose example for ceph, kafka, postgres cluster

That is how it can be done:

docker simple starter

Build and run (on linux do not forget sudo):

docker image build -t <image-name> .
docker container run --env "DOCKER=true" --env "NODE_ENV=test" --env "NODE_PORT=8000" --mount "type=bind,source=/etc/nginx/sites-enabled,target=/sites-enabled" --env "PATH_CONF=/sites-enabled" -p 8000:8000 --rm --name <container-name> --network=host <image-name>

docker container exec -it <container-name> bash

docker-compose for starting aerospike and memcache

Place this config wherever you like (in your project) — for instance, ~/myproj/docker/docker-compose.yml:

version: "2"

services:
  #aerspike
  as:
    image: aerospike/aerospike-server
    volumes:
      - ./aerospike/etc:/opt/aerospike/etc
    ports:
      - 3000:3000

    command: [asd, --config-file, /opt/aerospike/etc/docker.conf]

  memcached:
    image: memcached
    ports:
      - 11211:11211


volumes:
  #volume for etcd
  dicovery-data:
    driver: local

  #volume for database
  db-data:
    driver: local

version: "2"

services:

#aerspike

as:

image: aerospike/aerospike-server

volumes:

- ./aerospike/etc:/opt/aerospike/etc

ports:

- 3000:3000

command: [asd, --config-file, /opt/aerospike/etc/docker.conf]

memcached:

image: memcached

ports:

- 11211:11211

volumes:

#volume for etcd

dicovery-data:

driver: local

#volume for database

db-data:

driver: local

And this config for aerospike should be placed in a directory ~/myproj/docker/aerospike/etc/docker.conf After that you should run it like that:

cd ~/myproj/docker
docker-compose up -d

1 2	cd ~/myproj/docker docker-compose up -d

When you finished, just run:

cd ~/myproj/docker
docker-compose down

1 2	cd ~/myproj/docker docker-compose down

Запустить memcached в докере

Под мак.

docker pull memcached:alpine
docker run --name memcached -d --restart=always --publish 11211:11211 memcached:alpine
telnet localhost 11211
ctrl+]
docker ps
docker stop <id>

docker pull memcached:alpine

docker run --name memcached -d --restart=always --publish 11211:11211 memcached:alpine

telnet localhost 11211

ctrl+]

docker ps

docker stop <id>

Docker. Полезные команды

Обновить версию образа докера

sudo docker pull [path-to-registry]:master

1	sudo docker pull [path-to-registry]:master

Запустить shell-команду внутри докер-контейнера

sudo docker run -ti [path-to-registry]:master ls -la /views/desktop/pm-widgets

1	sudo docker run -ti [path-to-registry]:master ls -la /views/desktop/pm-widgets

Как собрать и запустить свой докер

cd ~/Documents/docker/
git clone git@github.com:bullgare/docker-golang.git
cd ./docker-golang/
docker build -t "bullgare:golang" .
docker run -d bullgare:golang
docker ps
docker exec -ti <container id> /bin/bash

cd ~/Documents/docker/

git clone git@github.com:bullgare/docker-golang.git

cd ./docker-golang/

docker build -t "bullgare:golang" .

docker run -d bullgare:golang

docker ps

docker exec -ti <container id> /bin/bash
