Essentially, the Docker approach boils down to downloading an unsigned binary, running it, and hoping it doesn’t contain any backdoor into your companies network. Feels like downloading Windows shareware in the 90s to me. When will the first docker image appear which contains the Ask toolbar? The first internet worm spreading via flawed docker images?Source: The sad state of sysadmin in the age of containers There’s certainly some truth to that. I’m not entirely sure that the compile-from-source approach was actually that much more secure as it was practically impossible to verify the source code anyway. At which point it makes little to no difference if you’re downloading random binaries off the internet or random source code – either way you’re implicitly trusting the source. Verifying signatures for the stuff you download would be a big improvement and many of the newer deployment approaches are very lacking in this area, but it still depends on having a trustworthy way of getting the signature to verify.
