Lab 4.1, Step 5- broken LaTeX

In the pdf for Lab 4.1, Step 5, the command to view the status of the cluster is incomplete, resulting in a "broken" Step 6. due to LaTeX being confused about the quotes. This seems like the right place to send a bug report of this sort... I suspect the command is supposed to end with something like '...etcdctl endpoint status -w table'
The step appears as follows, with visible LaTeX commands:
student@master: ̃$ kubectl -n kube-system exec -it etcd-master -- sh -c "ETCDCTL_API=3 \ ETCDCTL_CACERT=/etc/kubernetes/pki/etcd/ca.crt ETCDCTL_CERT=/etc/kubernetes/pki/etcd/server.crt \ ETCDCTL_KEY=/etc/kubernetes/pki/etcd/server.key etcdctl --endpoints=https://127.0.0.1:2379 \ \begin{response} +----------------------------+------------------+---------+---------+-----------+---- --------+-----------+------------+--------------------+--------+ | ENDPOINT | ID | VERSION | DB SIZE | IS LEADER | IS LEARNER | RAFT TERM | RAFT INDEX | RAFT APPLIED INDEX | ERRORS | +----------------------------+------------------+---------+---------+-----------+---- --------+-----------+------------+--------------------+--------+ | https://10.128.15.193:2379 | 4ef398947c14d552 | 3.4.9 | 4.2 MB | true | false | 2 | 2315318 | 2315318 | | +----------------------------+------------------+---------+---------+-----------+---- --------+-----------+------------+--------------------+--------+ \end{response} \item Now that we know how many etcd databases are in the cluster, and their health, we can back it up. Use the \verb?snapshot? argument to save the snapshot into the container data directory\file{/var/lib/etcd/} \begin{cmd} student@master: ̃$ kubectl -n kube-system exec -it etcd-master -- sh -c "ETCDCTL_API=3 \ ETCDCTL_CACERT=/etc/kubernetes/pki/etcd/ca.crt ETCDCTL_CERT=/etc/kubernetes/pki/etcd/server.crt \ ETCDCTL_KEY=/etc/kubernetes/pki/etcd/server.key etcdctl --endpoints=https://127.0.0.1:2379 \ snapshot save /var/lib/etcd/snapshot.db "

Hi @jecoulte,
This issues has been reported and solutioned in an earlier post, where you can find the full command:

Labs 4.1 - In step 3, the comment in command says to "pass the peer cert and key" but I see server.crt being passed in, can anyone please help me understand this?
student@master:˜$ kubectl -n kube-system exec -it etcd-master -- sh \ #Same as before
-c "ETCDCTL_API=3 \ #Version to use
ETCDCTL_CACERT=/etc/kubernetes/pki/etcd/ca.crt \ # Pass the certificate authority
ETCDCTL_CERT=/etc/kubernetes/pki/etcd/server.crt \ #Pass the peer cert and key
ETCDCTL_KEY=/etc/kubernetes/pki/etcd/server.key \
etcdctl endpoint health" #The command to test the endpoint
1 https://127.0.0.1:2379 is healthy: successfully committed proposal0 -
Hi @vishwas2f4u,
You can pass either the
server.crt
together withserver.key
, or pass thepeer.crt
together withpeer.key
instead.Regards,
