We can securely pull the code from Github using the Dockerfile RUN instruction. The code will be available when we start the container. Though this creates a security risk we can pull the public Github repo directly into the Docker image while building. We can use the RUN instruction with the git clone command in the Dockerfile as below, FROM ubuntu

Docker provides the RUN instruction to execute the commands directly inside the container while building the image. The third method is to run the git clone command directly. We can use a favourite editor to edit the code locally and then attach the directory as a volume to the running container and check the changes This is commonly used feature when developing code. This command start a container attaching the current working directory mounted as a volume to the container on /tmp. This can be done as, docker run -d -name my-source-project -v '$PWD':/tmp gitdocker We need to checkout the latest source code to a directory and mount the directory as a volume to the running container. The running container can share the files with the host machine. Using volumes we can mount a local directory to the container at runtime. The second method is the most commonly used way of sharing local content with the container. We can use a favorite editor to edit the code locally and then attach the directory as a volume to the running container and check the changes. This is a commonly used feature when developing code. This command starts a container attaching the current working directory mounted as a volume to the container on /tmp. COPY and ADD techniques are most commonly used in production to build production-ready Docker images docker run -d -name my-source-project -v '$PWD':/tmp gitdocker

ADD has the extra capability of fetching remote URLs and extracting tarballs. Once we build the Docker image, the code is copied to the /home/sampleTest directory and will be available once we run the container. The source code needs to be cloned to the current directory where the Dockerfile exists. A simple Dockerfile will look something like this: FROM ubuntu Using COPY or ADD Commandĭocker provides both COPY and ADD instructions for adding files/code to the Docker image. In this post, we will see how we can clone a Github public and private repo using oauth tokens and with ssh keys. There are multiple ways of getting code into the Docker container. In this article, we will see the various ways of getting the code to the Docker container. One common situation that I run into on different projects is how to tell my Docker container to clone or pull code automatically.
