Build Couchbase local environment with Docker

Overview

A memo when building a local environment of Couchbase with Docker

background

There was a local environment for Vagrant, --Startup and build are heavy --No code (black boxed) --Vagrant No one on the team understands (because of the environment created by the person who left the company) There are problems such as.

Purpose

Replace the local environment with Docker.

Work log

Try moving the couchbase image.

First, let's launch the Couchbase container without making detailed settings.

-Check the image at Couchbase docker hub repository

→ Since the version of the production environment is 4.5.1, use community-4.5.1.

--Start the container

For the time being, start as described in Description

$ docker run -d --name db -p 8091-8094:8091-8094 -p 11210:11210 couchbase:community-4.5.1

--Container startup confirmation

$ docker ps

↓ Start OK

--Console operation check

Access http://0.0.0.0:8091/ with a browser and confirm that the Couchbase console is displayed. You can manually set the account and bucket by pressing Setup, but since the purpose is coding, we will skip it here.

Check the operation for the time being. ..

Coded

Create Dockerfile, docker-compose.yaml

The following settings are required to set up the local environment. --Create cluster --Service settings --Couchbase server credentials settings --Bucket creation --View settings

Dockerfile (also docker-compose.yaml) is described in order to put the above settings into the code.

--Container execution with docker-compose

$ docker-compose up -d mbe-couchbase

Confirm bucket startup.

Impressions

Couchbase doesn't find many articles even if I google. The official reference was solid and it was just a simple implementation so I didn't have any problems. .. Is Couchbase not popular? It seems that the cloud version came out a while ago, but I don't think it will be used when relocating to the cloud.
