ARM64 on linux

This project just contain notes and examples to help me setup and run examples on aarm64.

Try running a arm64v8 container

$ docker run --rm -ti arm64v8/fedora uname -m
standard_init_linux.go:211: exec user process caused "exec format error"

So we need to install a few things go get this working...

Install QEMU

$ sudo dnf -y install qemu qemu-user qemu-user-static
$ docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

After this we should be able to run the same container we tried above:

$ docker run --rm -ti arm64v8/fedora uname -m
aarch64

Build a container

$ docker build -t aarch64-nodejs .

Running the container

$ docker run -ti aarch64-nodejs bash

Cloning a specific version/tag of Node.js:

$ git clone --depth 1 --branch v14.15.4 https://github.com/nodejs/node.git node
$ cd node
$ ./configure && make -j8

Tagging and pushing to docker hub

$ docker login -u <username>
$ docker tag aarch64-node-14.15.4 dbevenius/aarch64-node:14.15.4
$ docker push dbevenius/aarch64-node:14.15.4

Testing yarn

This was actually the purpose of this repo to test an issue when running yarn.

[root@5fde00944ba7 node]# uname -m
aarch64

$ export PATH=/node:$PATH
$ node --version
v14.15.4

$ /node/deps/npm/bin/npm-cli.js --version
6.14.10

$ mkdir yarn-test && cd yarn-test
$ /node/deps/npm/bin/npm-cli.js init
$ /node/deps/npm/bin/npm-cli.js  install -g yarn --unsafe-perm
$ /node/out/bin/yarn init 
$ /node/out/bin/yarn install
yarn install v1.22.10
[1/4] Resolving packages...
success Already up-to-date.
Done in 3.11s.
/node/out/bin/yarn list
...
Done in 3.53s.

Now I want to try the same using a binary of Node:

$ mkdir binary-node
$ cd binary-node/
$ curl https://nodejs.org/dist/v14.15.4/node-v14.15.4-linux-arm64.tar.gz | tar xpfz -
$ cd node-v14.15.4-linux-arm64/
$ export PATH=$PWD/bin:$PATH
$ which node
/node/binary-node/node-v14.15.4-linux-arm64/bin/node
$ mkdir sample
$ cd sample
$ npm init
$ npm install -g yarn --unsafe-perm
$ yarn add lodash
yarn add v1.22.10

[root@5fde00944ba7 sample]#

And that also works.

Troubleshooting

I'm not sure how I managed to get my system into this state but somehow I was not able to install qemu-user-static:

$ sudo dnf -y install qemu-user-static

I turned out I had a /usr/bin/qemu-arm-static:

$ sudo rm -rf /usr/bin/qemu-arm-static

AWS

For this I created and launched a new instance using RHEL 8 and arm64.

$ ssh -i path_to_aws_key ec2-user@public_dns

Install utils and build node:

$ sudo dnf install -y git gcc-c++ which make python3 openssl-devel procps-ng
$ git clone --depth 1 --branch v14.15.4 https://github.com/nodejs/node.git node
$ cd node
$ ./configure --debug && make -j2
