Here is the contents of my Dockerfile
cat Dockerfile
FROM alpine:3.8
COPY server.xml /tmp
RUN sed -i ‘1,/redirectPort=“8443”/ s//redirectPort=“8443” relaxedQueryChars=“[]”/’ /tmp/server.xml

If the alpine version is changed to anything lower than 3.8, noticing failure in “docker build”.
Error message noticed :- “sed: no previous regexp”
If the alpine version is 3.8, noticing no failure in “docker build”.

Pls let know whether it is a bug or any thing else needs to be done to execute the sed command with success. The version being used currently is 3.4
