I am trying to build a docker image that is provisioned with chef. It works for me with the following Dockerfile and chef recipe.
#Dockerfile
FROM centos:7
RUN yum install -y wget
RUN wget https://packages.chef.io/stable/el/7/chefdk-0.13.21-1.el7.x86_64.rpm
RUN yum install -y chefdk-0.13.21-1.el7.x86_64.rpm
COPY cookbooks cookbooks
RUN cd cookbooks/hs_price_verification && berks install && berks vendor cookbooks && chef-client -z --override-runlist hs_price_verification
#default.rb
include_recipe 'git'
package 'yum-utils'
execute 'yum --enablerepo=base clean metadata'
execute 'yum update -y || true'
execute 'yum-config-manager --enable cr'
domain=node['domainsname']
However if I move chef-client command to its own RUN line in the Dockerfile
...
RUN cd cookbooks/hs_price_verification && berks install && berks vendor cookbooks
RUN chef-client -z --override-runlist hs_price_verification
I get an error
================================================================================
Error Resolving Cookbooks for Run List:
================================================================================
Missing Cookbooks:
------------------
No such cookbook: git
Its like the results of 'berks install && berks vendor cookbooks' is on available on the same line of the Dockerfile and when I move the command the 'cache' is lost.
Can anyone explain?
Docker runs each RUN line in its own command, this means that the cd from the line before has no effect there.
