Question

In kubernetes, if you have a container running in a pod called 'test-deployment-abcd", issue command to get access to all the logs the container app is sending to stdout:

Answer

kubectl logs test-deployment-abcd

^^ note for "kubectl logs", "kubectl exec", "kubectl run" commands you don't need to follow up with resource type "pod", just follow up with pod name (or new deployment name in case of "kubectl run")

In kubernetes, if you have a container running in a pod called "test-deployment-abcd", issue command to get inside that container shell (to debug for example)?

Answer

kubectl exec -it test-deployment-abcd /bin/bash

Question

In kubernetes, if you have a container running in a pod, that exposes a web server through some port, since the pod only has an internal IP within the cluster and say you have no public IP for the pod using kubernetes "service" approach, how can you access the webserver? (answer contains two steps)

Answer

Through using "kubectl proxy", and then doing curl to the API endpoint of the pod

^^ note that "kubectl proxy" command creates a proxy process through which you can hit the endpoints of your cluster

^^^ note that "kubectl proxy" does not return any output and just keeps running in the shell till you ctrl-c/termintate it, so run it from a seperate terminal than your curl command

^^^^ the curl command would be something like: curl http://localhost:8001/api/v1/namespaces/default/pods/$POD_NAME/proxy/ , where 8001 is port proxy is running on

Background: Vitamin D deficiency has been declared a public health problem for both adults and children worldwide. Asthma and related allergic diseases are the leading causes of morbidity in children. The objective of this study was to investigate the potential role of Vitamin D deficiency in childhood asthma and other allergic diseases such as allergic rhinitis and wheezing. Materials and Methods: This cross‑sectional study was conducted in Primary Health Care Centers (PHCs), from March 2012 to October 2013. A total of 2350 Qatari children below the age of 16 were selected from PHCs, and 1833 agreed to participate in this study giving a response rate of (78%). Face‑to‑face interviews with parents of all the children were based on a questionnaire that included variables such as socio‑demographic information, assessment of nondietary covariates, Vitamin D intake, type of feeding, and laboratory investigations. Their health status was assessed by serum Vitamin D (25‑hydoxyvitamin D), family history and body mass index. Results: Most of the children who had asthma (38.5%), allergic rhinitis (34.8%) and wheezing (35.7%) were below 5 years. Consanguinity was significantly higher in parents of children with allergic rhinitis (48.6%), followed by those with asthma (46.4%) and wheezing (40.8%) than in healthy children (35.9%) (P < 0.001). The proportion of severe Vitamin D deficiency was significantly higher in children with wheezing (23.4%), allergic rhinitis (18.5%), and asthma (17%) than in healthy children (10.5%). Exposure to the sun was significantly less in Vitamin D deficient children with asthma (60.3%), allergic rhinitis (62.5%) and wheezing (64.4%) than in controls (47.1%) (P = 0.008). It was found that Vitamin D deficiency was a significant correlate for asthma (odds ratio [OR] =2.31; P < 0.001), allergic rhinitis (OR = 1.59; P < 0.001) and wheezing (relative risk = 1.29; P = 0.05). Conclusion: The study findings revealed a high prevalence of Vitamin D deficiency in children with asthma and allergic diseases. Vitamin D deficiency was a strong correlate for asthma, allergic rhinitis and wheezing
