A.2.3 ホスト情報変更用シェルスクリプト

Dockerコンテナのホスト名を変更するためのホスト情報変更用シェルスクリプト(chhostname.sh)の記述例を以下に記載します。

#!/bin/sh
DIR=`dirname $0`
HOST=`/usr/bin/hostname`; export HOST
COMMON_PATH=${DIR}/backup ; export COMMON_PATH

if [ -f ${DIR}/hostname ] ; then
  PRE_HOSTNAME=`/usr/bin/cat ${DIR}/hostname`
else
  PRE_HOSTNAME=""
fi

/usr/bin/date > ${DIR}/chhostname.log 2>&1

while :
do
  /opt/FJSVisjmx/bin/isjmxstat >> ${DIR}/chhostname.log 2>&1
  if [ $? -eq 1 ] ; then
    break
  fi
  sleep 1
done
if [ "${PRE_HOSTNAME}" != "${HOST}" ] ; then
  if [ ! -d ${COMMON_PATH} ] ; then
    /bin/csh -f ${DIR}/isbackup >> ${DIR}/chhostname.log 2>&1
  fi
  if [ $? -eq 0 ] ; then
    /bin/csh -f ${DIR}/isimport >> ${DIR}/chhostname.log 2>&1
  fi
  if [ $? -eq 0 ] ; then
    /opt/FJSVod/bin/OD_set_env -n ${HOST} >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} InterfaceRep \
          >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} InterfaceRep_e \
          >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} InterfaceRepLock \
          >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} InterfaceRepository \
          >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} InterfaceRepository_e \
          >> ${DIR}/chhostname.log 2>&1
    /opt/FJSVod/bin/odchgservice -h ${HOST} NameService \
          >> ${DIR}/chhostname.log 2>&1
    echo ${HOST} > ${DIR}/hostname
    exit 0

  else
    /usr/bin/rm -fr ${DIR}/hostname
  exit 1
  fi
else
    echo "hostname is ${HOST}. It is same as the one used at a previous time." >> ${DIR}/chhostname.log
    exit 0
fi
