构建

新建build.conf、build.sh

build.conf

DOCKER_IMAGE_NAME=centos-memcache-supervisor
DOCKER_IMAGE_TAG=latest
DOCKER_IMAGE_REPOSITORY_NAME=${DOCKER_USER}/${DOCKER_IMAGE_NAME}:${DOCKER_IMAGE_TAG}

build.sh

#!/usr/bin/env bash

# Change working directory
DIR_PATH="$( cd "$( echo "${0%/*}" )"; pwd )"
if [[ $DIR_PATH == */* ]]; then
cd $DIR_PATH
fi

NO_CACHE="$1"

source build.conf

show_docker_image ()
{
NAME=$1
NAME_PARTS=(${NAME//:/ })

# Set 'latest' tag if no tag requested
if [ ${#NAME_PART[@]} == 1 ]; then
NAME_PARTS[1]='latest'
fi

docker images | grep -e "^${NAME_PARTS[0]}[ ]\{1,\}${NAME_PARTS[1]}"
}

echo Building ${DOCKER_IMAGE_REPOSITORY_NAME}...

# Allow cache to be bypassed

# Build from working directory
docker build --no-cache=$NO_CACHE -t ${DOCKER_IMAGE_REPOSITORY_NAME} .

# Display the last docker image
