  A search for resonance-like structures in the
$\mathrm{B}^{0}_{\mathrm{s}}\pi^{\pm}$ invariant mass spectrum is performed
using proton-proton collision data collected by the CMS experiment at the LHC
at $\sqrt{s} = $ 8 TeV, corresponding to an integrated luminosity of 19.7
fb$^{-1}$. The $\mathrm{B}^{0}_{\mathrm{s}}$ mesons are reconstructed in the
decay chain $\mathrm{B}^{0}_{\mathrm{s}} \rightarrow \mathrm{J}/\psi\,\phi$,
with $\mathrm{J}/\psi \rightarrow \mu^+\mu^-$ and
$\phi\rightarrow\mathrm{K^{+}}\mathrm{K^{-}}$. The
$\mathrm{B}^{0}_{\mathrm{s}}\pi^{\pm}$ invariant mass distribution shows no
statistically significant peaks for different selection requirements on the
reconstructed $\mathrm{B}^{0}_{\mathrm{s}}$ and $\pi^{\pm}$ candidates. Upper
limits are set on the relative production rates of the X(5568) and
$\mathrm{B}^{0}_{\mathrm{s}}$ states times the branching fraction of the decay
$\mathrm{X}(5568)^{\pm} \rightarrow \mathrm{B}^{0}_{\mathrm{s}} \pi^{\pm} $. In
addition, upper limits are obtained as a function of the mass and the natural
width of possible exotic states decaying into
$\mathrm{B}^{0}_{\mathrm{s}}\pi^{\pm}$.
