Why did you remove static compilation?

The static link in docker was only added to work around the SIGSEGVs in alpine. Now with the build in Docker and with the matching libc runtime FROM ubuntu, the static build is no longer required.

Compiling binary statically has another side effect of having all dependencies compiled into binary, ensuring the resulting executable is assembled and equipped with all dependencies it was compiled with, ensuring consistency.

@C0rWin are you proposing that we change the make target to generate a static executable? I thought we had settled on the use of Docker to establish consistency across runtimes. Recall that the above update ENV CGO_ENABLED 0 was new behavior introduced in the release 2.5 alpha builds for alpine - the behavior in this PR reverts to the same mechanisms we've been using in Fabric since ~2017, with the primary difference that the base Docker image is now derived from ubuntu. Running with the ubuntu / gnu libc seems to have resolved all of the errors encountered with alpine's musl runtime.
Also:
-
Formal release binaries are static, generated with the golang cross-compiler.
-
Changing the default
maketarget to a static build will cause major issues for the pkcs11 runtimes.

Looks like ubuntu:20.04 has been on a tighter diet than debian:slim. This is on the arm64 - also on amd64 the debian images are a few MB larger. |

Description
This PR switches the Fabric base docker images from golang-alpine to ubuntu:20.04. The upgrade is necessary as the golang-alpine libc runtimes (musl) are incompatible with the requirements on multi-arch runtimes.
The motivations for this upgrade are described in detail in Discussion #3876 and comments in DRAFT PR #3877
