下面脚本的功能是循环地在各个container中执行命令:

#!/bin/bash -x

for i in {1..2}
do
        docker exec -i hammerdb_net${i} bash <<-EOF
        su oracle
        source /tmp/ora_env
        cd /data/oracle/tablespaces/
        rm -f *.html
        ./create_awr.sh
        mv awr.html awr_${i}.html
        EOF
done

需要注意的是在dodone之间应该使用tab而不是空格。
