A new task of mine is to get these applications into Docker containers to run independently inside a bigger ..
Currently I have a spring application which was made to run on docker for which we have followed this documentation mentioned below: https://spring.io/guides/gs/spring-boot-docker/ This I believe this command docker build -t springio/gs-spring-boot-docker . builds an image for x86 platform only. As I’m using an x86 machine for development, how does one build a docker image ..
Background I am running the qemu-arm user space emulator inside of a Docker container on Docker for Mac. I am working on a code base that runs on cortex-m4 processors. I want to be able to cross-compile the code in the docker container to target the cortex-m4 processor and run that code on the qemu-arm ..
I’m trying to build an arm64 Docker image for a Spring Boot app which uses multi-stage build. buildx or rather qemu hangs on unpacking step using jar -xf ../*.jar. One of the CPU cores uses 100% and the process runs infinitely. At the same time buildx can successfully build arm64 images for my non-Java projects. ..
I just setup a x86-64 environment on arm64 M1 Mac Mini with the Ubuntu Docker image. I’ve installed relevant softwares such as the GCC AArch64 cross compiler, and user-mode QEMU. I know this setup works on Windows Subsystem for Linux (also the Ubuntu distribution), except for the SPARC-64 emulation is failing. But when doing this ..
I have a scenario where I’m provided access to a customer’s AWS environment (except to the code base) and the customer is having their images present on AWS ECR. I have an EKS kubernetes node pool which consists of Graviton (ARM) servers. I have a requirement to rebuild the image from the existing one to ..
I want to run a docker container for Ganache on my MacBook M1, but get the following error: The requested image’s platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested After this line nothing else will happen anymore and the whole process is in stuck, although the qemu-system-aarch64 ..
I have cross-compiled valgrind 3.13 using the arm-linaro toolchain with command: ./configure –target=arm-none-linux-gnueabi –host=armv7-none-linux-gnueabi –prefix=/home/karan/valgrind/build CFLAGS=-static CPPFLAGS=-fPIC CFLAGS=-fPIC make && make install I have transferred the valgrind build folder on the docker container( docker image: https://hub.docker.com/r/arm32v7/ubuntu in directory= /root/valgrind/build) and exported the PATH environment variable as well as VALGRIND_LIB variable. After this when I try ..
I own an instance at Oracle Cloud that is running on ARM64 platform. I try to run the headless Chrome Docker instance, but it always fails. What did I do: Built a docker image Wrote a small JS snippet that uses the Puppeteer to make screenshots Ran all the things together against https://example.com in order ..
