[UPDATE: Revise instructions and links to use latest upstream nabla repo
with merged aarch64 support.]
In previous posts, we covered a bit of background on
rumprun, the nabla containers fork and our port on aarch64. In
this post, we describe how to build everything from source. In order to build a
rumprun unikernel for aarch64, the first step is to build the rumprun
toolchain.
Clone the relevant repositories:
1git clone https://github.com/nabla-containers/rumprun
2git clone https://github.com/cloudkernels/rumprun-packages
1cd rumprun
2git submodule update --init
Build rumprun with:
1cd rumprun
2make
The build is tested with gcc-5 but it should work with gcc versions up to 6. If you need to explicitly set the gcc version use:
1cd rumprun
2CC=<gcc-version> make
Solo5 is now built by default as part of the nabla-containers code distribution.
Build (& bake) hello (both hvt and spt versions):
1cd rumprun-packages
2cd hello
3make
Output is the following:
1mkdir -p build
2cp src/* build
3CC=aarch64-rumprun-netbsd-gcc make -C build hello.spt
4make[1]: Entering directory '/build/rumprun-packages/hello/build'
5aarch64-rumprun-netbsd-gcc hello.c -o hello-rumprun
6rumprun-bake solo5_spt hello.spt hello-rumprun
7
8!!!
9!!! NOTE: rumprun-bake is experimental. syntax may change in the future
10!!!
11
12make[1]: Leaving directory '/build/rumprun-packages/hello/build'
13mkdir -p bin
14cp build/hello.spt bin/hello.spt
15CC=aarch64-rumprun-netbsd-gcc make -C build hello.hvt
16make[1]: Entering directory '/build/rumprun-packages/hello/build'
17rumprun-bake solo5_hvt hello.hvt hello-rumprun
18
19!!!
20!!! NOTE: rumprun-bake is experimental. syntax may change in the future
21!!!
22
23make[1]: Leaving directory '/build/rumprun-packages/hello/build'
24mkdir -p bin
25cp build/hello.hvt bin/hello.hvt
Try to run both (an existing dummy file and tap0 device are expected):
1../../rumprun/solo5/tenders/hvt/solo5-hvt --disk=dummy --net=tap0 ./bin/hello.hvt
Output:
1solo5-hvt: bin/hello.hvt: Warning: phdr[0] requests WRITE and EXEC permissions
2solo5-hvt: WARNING: Tender is configured with HVT_DROP_PRIVILEGES=0. Not dropping any privileges.
3solo5-hvt: WARNING: This is not recommended for production use.
