I am using docker on a mac.
you tried to call a command
“/bin/sh -c apt-get…”
it then complains that it cannot find an executable called “/bin/sh -c …”. Sure.
The command should look like
/bin/sh -c “apt-get -y update …”
or shorter like
apt-get -y update

####installing supervisor
RUN apt-get -y update && apt-get install -y supervisor
was my exact command inside my dockerfile.
am following https://docs.docker.com/engine/admin/using_supervisord/ url… except that am not using ubuntu…
should work…can you paste your whole Dockerfile - or even better automate your docker image build with docker hub? then easily could help you.
PS: using supervisord and similar tools within a docker container is considered a bad practice. try to split your containers so that each of them is just running one command, one process.
the below is my complete docker file (plz note the ### were showing as comments in bold)
FROM java:8-alpine

####installing supervisor
RUN apt-get -y update && apt-get install -y supervisor

apt-get works on ubuntu, you are using java8-alpine…a mini-linux-distro. There you need to use apk for example.
Thank you, I love this comment.
I saved time.
