Image Service

This is the Image service

Generated with

micro new image-srv --namespace=go.micro --type=srv

Getting Started

• Configuration
• Dependencies
• Usage
• Example

Configuration

• FQDN: go.micro.srv.image
• Type: srv
• Alias: image

Dependencies

Micro services depend on service discovery. The default is multicast DNS, a zeroconf system.

In the event you need a resilient multi-host setup we recommend consul.

# install consul
brew install consul

# run consul
consul agent -dev

Besides the service discovery, the image service depends on the blob service which provides filesystem storage functionality. You can get is usual way:

go get github.com/microhq/blob-srv

Usage

A Makefile is included for convenience

Build the binary

make build

Run the service

./image-srv

Build a docker image

make docker

Example

Start blob service:

MICRO_REGISTRY=consul blob-srv
