Containerizing​ Oracle Cloud Infrastructure (OCI) Command Line Interface (CLI)


Oracle Cloud Infrastructure (OCI) command line interface (CLI) is one of several methods provided for managing the Oracle cloud infra generation 2.

The CLI can be installed and configured in your local machine just following the instructions in the documentation.

In this post, we are explaining an alternate method for using the CLI by means of creating a container. Main advantage: portability and encapsulation of configurations just in case you are managing more than one tenant.

STEP 1

Install and configure OCI CLI. Please notice that a hidden folder called .oci gets created in your home directory:

ocloudshell1

STEP 2

Create a directory for creating the container, let’s call it ocloudshell for instance:

mkdir ocloudshell

STEP 3

copy ./oci directory in your home directory to ocloudshell dir

STEP 4

Edit the ./oci/config file and change the absolute paths to be relative to the home directory. For instance, in my mac is as follows:

ocloudshell2

ocloudshell3

STEP 5

Download the OPC CLI and put it in the ocloudshell dir

STEP 6

Create Dockerfile as follows:

FROM store/oracle/serverjre:8
ENV LC_ALL=en_US.utf8 \
LANG=en_US.utf8
ARG OPC_CLI_VERSION=18.1.2
ENV OPC_CLI_PKG=opc-cli-$OPC_CLI_VERSION.zip
WORKDIR /ocloudshell/
RUN curl -o /etc/yum.repos.d/public-yum-ol7.repo http://yum.oracle.com/public-yum-ol7.repo \
&& yum-config-manager --enable ol7_developer_EPEL \
&& yum-config-manager --enable ol7_developer \
&& yum -y install unzip python-oci-cli \
&& rm -rf /var/cache/yum/*
WORKDIR /root
ADD .oci/ .oci/
RUN chmod 400 .oci/config
RUN chmod 400 .oci/oci_api_key.pem
CMD ["/bin/bash"]

STEP 7

Create the container and push it to a private repository!*
docker build -t myrepo/ocloudshell .

docker push myrepo/ocloudshell
(*) Don’t push the image to a public repo for obvious security reasons

 

TEST IT

So far, so good. Let’s test the container executing a command, here is the command reference documentation. For instance, let’s execute a command for starting a VM:

docker run -it javiermugueta/ocloudshell oci compute instance action --instance-id ocid1.instance.oc1.eu-frankfurt-1.abtheljtbocj2w4qywieacalgsortabg4kep77lplqfwfmlup77725rvsjxa --action start

That’s all folks!

Enjoy 🙂
