            proxying from containerized production react to containerized flask
            Asked 2021-Jun-15 at 16:20

            I am trying to proxy requests from my containerized React application to my containerized Flask application.

            I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.

            Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.

            Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.

            I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.

            If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.

            I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

            I have looked these solutions:

            How to run Sequelize migrations inside Docker
            Asked 2021-Jun-15 at 15:38

            I'm trying to docerize my NodeJS API together with a MySQL image. Before the initial run, I want to run Sequelize migrations and seeds to have the tables up and ready to be served.

            Here's my docker-compose.yaml:



            Answered 2021-Jun-15 at 15:38

            I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.

            My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touchs a semaphore file. If the file exists already, it skips the seeds.



            docker compose not exposing ports
            Asked 2021-Jun-14 at 18:42

            please try using docker-compose run -p 8080:80 deploy_test as run command can not expose/publish ports by itself i.e. you need to specify it manually. For more information regarding same, please refer to its official documentation here.



            How to check whether an app in Docker container ignores Java memory options?
            Asked 2021-Jun-14 at 11:21

            There is a Java 11 (SpringBoot 2.5.1) application with simple workflow:

            1. Upload archives (as multipart files with size 50-100 Mb each)
            2. Unpack them in memory
            3. Send each unpacked file as a message to a queue via JMS

            When I run the app locally java -jar app.jar its memory usage (in VisualVM) looks like a saw: high peaks (~ 400 Mb) over a stable baseline (~ 100 Mb).

            When I run the same app in a Docker container memory consumption grows up to 700 Mb and higher until an OutOfMemoryError. It appears that GC does not work at all. Even when memory options are present (java -Xms400m -Xmx400m -jar app.jar) the container seems to completely ignore them still consuming much more memory.

            So the behavior in the container and in OS are dramatically different. I tried this Docker image in DockerDesktop Windows 10 and in OpenShift 4.6 and got two similar pictures for the memory usage.




            Answered 2021-Jun-13 at 03:31

            In Java 11, you can find out the flags that have been passed to the JVM and the "ergonomic" ones that have been set by the JVM by adding -XX:+PrintCommandLineFlags to the JVM options.

            That should tell you if the container you are using is overriding the flags you have given.

            Having said that, its is (IMO) unlikely that the container is what is overriding the parameters.

            It is not unusual for a JVM to use more memory that the -Xmx option says. The explanation is that that option only controls the size of the Java heap. A JVM consumes a lot of memory that is not part of the Java heap; e.g. the executable and native libraries, the native heap, metaspace, off-heap memory allocations, stack frames, mapped files, and so on. Depending on your application, this could easily exceed 300MB.

            Secondly, OOMEs are not necessarily caused by running out of heap space. Check what the "reason" string says.

            Finally, this could be a difference in your app's memory utilization in a containerized environment versus when you run it locally.

            If you want to use kubernetes inside a docker container my suggestion is to use k3d .

            k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker.k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.

            You can Download , install and use it directly with Docker. For more information you can follow the official documentation from .

            To get the list of pods you dont' need to create a k8s cluster inside a docker container . what you need is a config file for any k8s cluster . ├── Dockerfile ├-- config └── 0 directories, 3 files

            DPDK Compilation fails inside WSL2 Docker Desktop's containers
            Asked 2021-Jun-13 at 14:09

            I can't compile DPDK inside a docker container, running under WSL2 as VM (and windows 10 as the host machine).


            Trying to compile DPDK locally inside a wsl-container some DPDK lib that used to be built on remote native linux machines.

            The Dockerfile running the compilation had installed kernel headers, GNU toolchain and other various dependencies. The distribution is CentOS7.

            The containers are managed by Docker Desktop

            Versions are useless information here.

            The Problem

            Similar problems across DPDK versions. In DPDK 20.11, using the meason build-system, the file kernel/linux/

            ../kernel/linux/ ERROR: Problem encountered: Cannot compile kernel modules as requested - are kernel headers installed?

            If I compile different DPDK versions of DPDK or building using other build-systems (makefiles), I am getting variants of the same error.

            Inside your /lib/modules has no entry with WSL2 "uname -r" output

            Although WSL2 has /lib/modules/5.4.72-microsoft-standard-WSL2 (as a softlink), this soft link does not appear in the container.

            The solution is adding this line to the Dockerfile*:

            Answered 2021-Jun-12 at 22:39

            You can't do this from command level. But I guess you could write container_commands script to rename your docker-compose file from to docker-compose.yml:

            You can use the container_commands key to execute commands that affect your application source code. Container commands run after the application and web server have been set up and the application version archive has been extracted, but before the application version is deployed.

            I tried to replicate the issue using simplified setup with just and Docker running on 64bit Amazon Linux 2 3.4.1 EB platform.
