Hi! We’re preparing to use Balena engine, however on our Linux platform we use sysVinit as an init system, and systemd is disabled. > ./balena-engine > ./balena-engine: error while loading shared libraries: libsystemd.so.0: cannot open shared object file: No such file or directory Is it possible to configure Balena Engine to run with sysVinit? I found this: > > > //github.com/balena-os/balena-engine/tree/master/contrib/init and this: [Debian package - remove SysVinit configuration because it's not used · Issue #30936 · moby/moby · GitHub](https://github.com/moby/moby/issues/30936) This topic also mentions that it is possible: [no systemd · Issue #87 · balena-os/balena-engine · GitHub](https://github.com/balena-os/balena-engine/issues/87) What are the steps to run the balena engine on a Linux device that has sysVinit as init system? Thanks, Filip ---

Hi there, it might be that it is now a requirement. I’ll check with the engine team and let you know. ---

Hi @tmigone! Do you know already of this is a hard requirement to have systemd? I sincerely hope it isn’t… 😉 ---

Hey, can you let us know where you are downloading the version of balena-engine you tried, or are you building it from source? You could try it with a build flag like `no_journald` to remove the systemd dependency. ---

So far we have tried the latest binary for armv6. I have just tried compiling the balena-engine, but I didn’t find any documentation on building from source. Please tell me if what I did is correct: Changed the flag from journald to no\_journald in [make.sh](https://github.com/balena-os/balena-engine/blob/master/hack/make.sh#L96): ```auto filip@prec:~/downloads/balena-engine$ git diff diff --git a/hack/make.sh b/hack/make.sh index ecd1288831..d91cd808af 100755 --- a/hack/make.sh +++ b/hack/make.sh @@ -93,9 +93,9 @@ add_buildtag() { } if ${PKG_CONFIG} 'libsystemd >= 209' 2> /dev/null ; then - DOCKER_BUILDTAGS+=" journald" + DOCKER_BUILDTAGS+=" no_journald" elif ${PKG_CONFIG} 'libsystemd-journal' 2> /dev/null ; then - DOCKER_BUILDTAGS+=" journald journald_compat" + DOCKER_BUILDTAGS+=" no_journald" fi ``` Then I have run make. Looks like it has created a container and run the build inside, and produced the binary of the daemon: ```auto filip@prec:~/downloads/balena-engine$ ls -l bundles/binary-daemon/ total 44588 lrwxrwxrwx 1 root root 17 lip 16 09:59 balena-engine -> balena-engine-dev -rwxr-xr-x 1 root root 45644336 lip 16 09:59 balena-engine-dev -rw-r--r-- 1 root root 52 lip 16 09:59 balena-engine-dev.md5 -rw-r--r-- 1 root root 84 lip 16 09:59 balena-engine-dev.sha256 ``` Is this correct? Another question: I want to build it for armv6 only. How to achieve that? ---

Ok, by grepping the repo I found this guide: [balena-engine/PACKAGERS.md at master · balena-os/balena-engine · GitHub](https://github.com/balena-os/balena-engine/blob/master/project/PACKAGERS.md) So I compiled with ```auto make DOCKER_CROSSPLATFORMS=linux/arm/v7 cross ``` And I got a binary for armv6 ```auto $ file bundles/cross/linux/arm/v6/balena-engine-dev bundles/cross/linux/arm/v6/balena-engine-dev: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, Go BuildID=23RRcf-7UnZBmEzbO5AH/_L4heeztWQRG3wI96n6k/Nt0bh7RxNHNDwKmLUfJ-/I4W21j2Mn7vv9ro88MI5, stripped ``` Hopefully will work on armv6 without systemd. ---

Hi @klutchell @tmigone. Do you maybe have a list of dependencies that Balena expects from the underlying Linux system? On our system, it looks like a few dependencies are missing: ```auto failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: Iptables not found ``` ```auto ERRO[2021-07-21T09:44:03.911698086Z] Failed to built-in GetDriver graph btrfs /var/lib/balena-engine ERRO[2021-07-21T09:44:03.914922995Z] Failed to built-in GetDriver graph zfs /var/lib/balena-engine ERRO[2021-07-21T09:44:04.170617814Z] AUFS was not found in /proc/filesystems storage-driver=aufs ERRO[2021-07-21T09:44:04.279133766Z] Failed to built-in GetDriver graph devicemapper /var/lib/balena-engine WARN[2021-07-21T09:44:04.459445702Z] Your kernel does not support swap memory limit WARN[2021-07-21T09:44:04.465744526Z] Your kernel does not support cgroup rt period WARN[2021-07-21T09:44:04.468153458Z] Your kernel does not support cgroup rt runtime WARN[2021-07-21T09:44:04.470562390Z] Your kernel does not support cgroup blkio weight WARN[2021-07-21T09:44:04.475898240Z] Your kernel does not support cgroup blkio weight_device WARN[2021-07-21T09:44:04.480019125Z] Your kernel does not support cgroup blkio throttle.read_bps_device WARN[2021-07-21T09:44:04.481125094Z] Your kernel does not support cgroup blkio throttle.write_bps_device WARN[2021-07-21T09:44:04.481408086Z] Your kernel does not support cgroup blkio throttle.read_iops_device WARN[2021-07-21T09:44:04.481615080Z] Your kernel does not support cgroup blkio throttle.write_iops_device WARN[2021-07-21T09:44:04.486189951Z] Unable to find cpuset cgroup in mounts ``` ---

Remember that our balenaEngine is just a fork of the Docker/moby project so the same dependencies would apply. In this case you could either install iptables or enable legacy iptables as per this forum post: > **[Failing to start dockerd: failed to create NAT chain DOCKER](https://forums.docker.com/t/failing-to-start-dockerd-failed-to-create-nat-chain-docker/78269/2)** > > The docker installer uses iptables for nat. Unfortunately Debian uses nftables. You can convert the entries over to nftables or just setup Debian to use the legacy iptables. sudo update-alternatives --set iptables /usr/sbin/iptables-legacy sudo... If any other dependencies are missing I would personally just search for answers on the Docker forums or the moby project GH as it’s more likely to have been answered there! ---

Good news is that balena-engine is already included in buildroot and most (not all) of the dependencies are taken care of: [buildroot/package/balena-engine at master · buildroot/buildroot · GitHub](https://github.com/buildroot/buildroot/tree/master/package/balena-engine) Kudos to Tian Yuanhao. It also cross-compiles to a correct architecture automatically, based on the information that buildroot already has. For future, here is the list of runtime dependencies of Balena Engine / Docker: >
