            Best practices while building docker images for spring boot app via gradle
            Asked 2022-Mar-31 at 18:39

            I am planning to use gradle as build tool with docker for containerizing spring boot applications.

            I currently have one question regarding best practices/pros/cons from:
            a. from general perspective as a best practice.
            b. from CI /CD perspective.

            I have understood that I can do it in three ways:

            1. Do gradle build by running command on your host machine + then dockerize your spring boot app

            eg:

            After almost 7 years of building Docker images from Gradle, long before Docker became a commonplace thing, I’ve never done option 2. I’ve done options 1 and 3, primarily 3.

            The problem with #1 is that you lose the information from your Gradle project that can be used to build the image, like the location of the jar file and the project name (there are several others). You end up redefining them on the command line, and the result could be very different.

            The problem with #2 is the loss of developer productivity and conflating responsibilities. I can’t imagine building a Docker image every time I made a change to the code. Gradle is a build tool, Docker is a delivery mechanism, and they have different goals.

            There are many articles that you can find online for building Docker images that apply equally well to Spring applications. Most notably:

            1. Use layers to avoid rebuilding code not changed.
            2. Use a Gradle Docker plugin to integrate Docker build within Gradle. I’m not sure if the Spring Boot plugin has integrated Docker build task now, if so, use that.
            3. Use a JRE as base instead of JDK if your code can live with that. Many projects don’t need JDK to run.

            Docker Compose accessing another container via localhost
            Asked 2022-Mar-01 at 16:12

            I am trying to wrap my head around how to access other containers running as part of docker-compose services.

            I have seen a lot of answers talking about containers accessible by their service name inside of other containers but also a lot of tutorials simply use the localhost with the exposed port.

            So I am just trying to gain clarity on when to use which and why it works the way it works.

            My sample application is: https://github.com/daniil/full-stack-js-docker-tutorial

            In it, I have an NGINX server that maps both ui and api services together, but after the fact I realized that inside of my React container (3000:3000) I can actually just get access to Express container (5050:5050) by making an axios request to http://localhost:5050.

            But at the same time if I try to connect to my MySQL container (9906:3306) via localhost, it doesn't work, I have to use db as a host, ie the container name.

            Can someone please help me understand how it all works:

            • When can I use http://localhost:SERVICE_PORT, does it work inside React service because it's a browser request? ie: axios
            • How come I can't use http://api:5050 inside of React / axios request, is it because there is no host resolution for that?
            • How come I can't use http://localhost:9906|3306 to connect to my db service?
            • What is the purpose or benefit of NGINX reverse proxy to tie client and api together, if you actually don't need to have anything in between since localhost seems to work?
            • If containers are supposed to isolated, why is it then localhost:5050 from within my React container still sees the API server running on 5050 in a different container?
            • Other general rules that can help me understand how cross-container communication works

            Answered 2022-Mar-01 at 16:12

            The important detail here is that your React application isn't actually running in a container. It's running in the end user's browser, which is outside Docker space, and so doesn't have access to Docker's internal networking.

            the issue is with the apostrophe ' you should be using apostrophes (in plural - otherwise known as quotation marks) "

            This command seems to be working for me

            (no changes needed on your behalf):

            docker container commit --change="CMD ['java','-jar','/tmp/mytroubleartifact-0.jar']" upbeat_brahmagupta a-repo-name-of-choice/some-app-name:tagname2

            though I've seen other people using a single apostrophe for me it also didn't work with your situation. docker docs example also didnt work with just copying the --change part, with both options (-c, --change) and with just one of them, only using double qoutes did the trick, not exactly sure why though. (tried replacing names, making them shorter ¯_(ツ)_/¯)

            docker commit --change='CMD ["apachectl", "-DFOREGROUND"]' -c "EXPOSE 80" c3f279d17e0a svendowideit/testimage:version4

            thanks to these posts for the working example:

            Is "Enable Docker" in VS project creation only adding the docker files or is there more magic to it?
            Asked 2021-Jul-03 at 11:48

            While creating a new project, there's the option to Enable Docker as depicted below. I've used containers for a while and set up my docker files manually, not as a part of any template. In fact, that's how I've taught myself once, looong time ago, and, frankly, never even thought of an alternative.

            I'm currently setting up a new project and I'm not sure what precisely (and I mean nerdly, academically precisely) that checkbox does to my creation. Googling the matter (proof of effort in links below) gave me a lot of great info but not the actual answer to whether the addition of the docker container definition actually is the only deviation from the usual template based project. It maybe is there and I'm simply to dense to realize it. Feel free to smack me in the back of my head if so is the case.

            I feel this is a very valid question, but without a very specific answer as provided by the OP.

            I would like to extend this to container tools not be specific to docker. Docker will be used as an example.

            I feel the answer is already answered here(provided by OP) -> https://docs.microsoft.com/en-us/visualstudio/containers/overview?view=vs-2019

            The tools included in Visual Studio for developing with containers are easy to use, and greatly simplify building, debugging, and deployment for containerized applications. You can work with a container for a single project, or use container orchestration with Docker Compose, Service Fabric, or Kubernetes to work with multiple services in containers.

            It does not only add the dockerfiles. We are getting other capabilities as well most probably specific to Visual Studio which allow for building and debugging with the aka F5 experience as mentioned above. Also, we can append to it with orchestrators such as Docker-Compose, Service Fabric and Kubernettes again with building and debugging capabilities with F5.

            As it can be seen very quickly by the below image, by just creating & enabling docker and docker compose orchestration support I am able to start the application using docker compose with F5 and also I have debugging capabilities out of the box. Also I can append to it with other services and add to the orchestrator with auto gen tools. Visual studio for most of these things will prompt to the user and it will fill Dockerfile and docker-compose files automatically. So we do not have to write any of the boilerplate infrastructure code.

            There is some difference in the templates, not really though, since you can add docker & orchestration support later in the project with some extra clicks. So you do not have to do it from the start

            Answered 2021-Apr-03 at 09:37

            I think that plugin requires the docker cli to be present. If you run jenkins as a docker image itself, use an image that provides the docker cli, for example https://hub.docker.com/r/trion/jenkins-docker-client

            If you want to use the host docker daemon for building, you need to bind-mount the docker socket. If you want to use a sidecar container to provide the docker daemon, for example using a docker-in-docker setup you can usually use the container name as docker host or kubernetes service name. This depends on how you provide the sidecar container and there is no general answer to that.

            The reason why it failed because the dependencies used by golang program are not available inside docker for it to build successfully.

            You are using dep for dependency management i.e. for your external libraries locally but have not installed any of them in the docker.

            You need to have them available in docker by having first dep tool within your container. The dep tool will ensure that your dependencies required by the package are available by dep ensure

            Also, you should ideally put your repository in the $GOPATH as mentioned below
