使用官方ceph-container工程构建私人定制的ceph/daemon镜像。本文以mimic版本为例，在对mimic进行二次开发后，将生成的rpm包更新到yum源中，再生成新的ceph-release中使用该yum源。

获取官方ceph-container

1	git clone git@github.com:ceph/ceph-container.git

安装私有Ceph.repo

修改获取ceph-releaseRPM包地址，编辑文件./ceph-releases/ALL/centos/daemon-base/__DOCKERFILE_INSTALL__。

eg:

yum install -y epel-release && \
yum install -y jq && \
bash -c ' \
  if [ -n "__GANESHA_PACKAGES__" ]; then \
    echo "[ganesha]" > /etc/yum.repos.d/ganesha.repo ; \
    echo "name=ganesha" >> /etc/yum.repos.d/ganesha.repo ; \
    if [[ "${CEPH_VERSION}" =~ master|^wip* ]]; then \
      REPO_URL=$(curl -s "https://shaman.ceph.com/api/search/?project=nfs-ganesha&distros=centos/__ENV_[BASEOS_TAG]__&flavor=ceph_master&ref=next&sha1=latest" | jq -a ".[0] | .url"); \
      echo "baseurl=$REPO_URL/\$basearch/" >> /etc/yum.repos.d/ganesha.repo ; \
    elif [[ "${CEPH_VERSION}" == nautilus ]]; then \
      echo "baseurl=http://download.ceph.com/nfs-ganesha/rpm-V2.8-stable/$CEPH_VERSION/\$basearch/" >> /etc/yum.repos.d/ganesha.repo ; \
    else \
      echo "baseurl=http://download.ceph.com/nfs-ganesha/rpm-V2.7-stable/$CEPH_VERSION/\$basearch/" >> /etc/yum.repos.d/ganesha.repo ; \
    fi ; \
    echo "gpgcheck=0" >> /etc/yum.repos.d/ganesha.repo ; \

    if [[ "${CEPH_VERSION}" =~ master|^wip* ]]; then \
      curl -s -L https://shaman.ceph.com/api/repos/ceph-iscsi/master/latest/__ENV_[BASEOS_REPO]__/__ENV_[BASEOS_TAG]__/repo > /etc/yum.repos.d/ceph-iscsi.repo ; \

yum update -y && \

bash -c ' \
  if [[ "${CEPH_VERSION}" =~ master|^wip* ]] || ${CEPH_DEVEL}; then \
    REPO_URL=$(curl -s "https://shaman.ceph.com/api/search/?project=ceph&distros=centos/__ENV_[BASEOS_TAG]__&flavor=default&ref=${CEPH_VERSION}&sha1=latest" | jq -a ".[0] | .url"); \
    RELEASE_VER=0 ;\
  else \
    RELEASE_VER=1 ;\
    REPO_URL="http://10.100.13.112/rpm-${CEPH_VERSION}/el__ENV_[BASEOS_TAG]__/"; \
  fi && \
  rpm -Uvh "$REPO_URL/noarch/ceph-release-1-${RELEASE_VER}.el__ENV_[BASEOS_TAG]__.noarch.rpm" ' && \
yum install -y __CEPH_BASE_PACKAGES__ && \
bash -c ' \
  if [[ "${CEPH_VERSION}" =~ master|^wip* ]] || ${CEPH_DEVEL}; then \
    yum install -y python-pip ; \
    pip install -U remoto ; \
    yum remove -y python-pip ; \
  fi '

REPO_URL使用您指定的yum源。

指定版本构建镜像

1	make FLAVORS=mimic-13.2.6-1.gba13b2d.el7,centos,7 build
