@Djelibeybi any deep wisdom as to how we can find zstd in OL7? 😬 I find a lot of things on the internet that claim it should be a thing that exists in OL7, but I can't seem to find it:

bash-4.2# grep -F '[' /etc/yum.repos.d/* | cut -d'[' -f2 | cut -d']' -f1 | sed 's/^/--enablerepo=/' | xargs -rt yum list available | grep zstd
yum list available --enablerepo=ol7_latest --enablerepo=ol7_u0_base --enablerepo=ol7_u1_base --enablerepo=ol7_u2_base --enablerepo=ol7_u3_base --enablerepo=ol7_u4_base --enablerepo=ol7_u5_base --enablerepo=ol7_u6_base --enablerepo=ol7_u7_base --enablerepo=ol7_u8_base --enablerepo=ol7_u9_base --enablerepo=ol7_optional_latest --enablerepo=ol7_addons --enablerepo=ol7_MODRHCK --enablerepo=ol7_leapp --enablerepo=ol7_latest_archive --enablerepo=ol7_optional_archive --enablerepo=ol7_security_validation --enablerepo=ol7_u8_security_validation --enablerepo=ol7_UEKR6 --enablerepo=ol7_UEKR5 --enablerepo=ol7_UEKR4 --enablerepo=ol7_UEKR3 --enablerepo=ol7_UEKR3_OFED20 --enablerepo=ol7_UEKR6_RDMA --enablerepo=ol7_UEKR5_RDMA --enablerepo=ol7_UEKR4_OFED --enablerepo=ol7_UEKR4_archive --enablerepo=ol7_UEKR5_archive --enablerepo=ol7_kvm_utils 
libzstd.i686                       1.4.4-1.el7              ol7_UEKR6           
libzstd.x86_64                     1.4.4-1.el7              ol7_UEKR5           
libzstd-devel.i686                 1.4.4-1.el7              ol7_UEKR6           
libzstd-devel.x86_64               1.4.4-1.el7              ol7_UEKR5           

(I'm sure there's a better way to do that --enablerepo= check too, but you know, short on spoons for yum right now given skip_missing_names_on_install is even a thing that exists and defaults to True)

If we can't fix this, I'll just plan to remove zstd from the list on 5.7 and call it a day, lol.

We disable the UEK repos inside the container images so that customers don't try and install a kernel inside a container. To install it, you will have to enable the repo on-the-fly:

$ yum --enablerepo=ol7_UEKR6 install -y libzstd

  libzstd.x86_64 0:1.4.4-1.el7

Complete!
bash-4.2#

But, at least it doesn't pull in any dependencies, like a kernel. :)

[tianon]

Heh, but that's just libzstd, and I need the command-line tool zstd 😇

[Djelibeybi]

Ha, I misunderstood the question. One moment, I'm checking.

[Djelibeybi]

It's in our EPEL repo, so:

yum -y install oracle-epel-release-el7
yum -y install zstd

[tianon]

Yay, it works! Thank you 😊
